Plenary Lectures

 

NicolaeNicolae-Victor Zamfir graduated Faculty of Physics of Bucharest in 1976, and afterwards started his career as a research scientist at the Horia Hulubei National Institute for R&D in Physics and Nuclear Engineering (IFIN-HH), in Magurele, getting his Ph.D in Nuclear Physics at the Central Institute of Physics in Bucharest, in 1984. From 1990 to 2004 he worked and taught in prestigious institutions in Germany and in the United States of America, as follows: 1990-1992, Visiting Scientist at the University of Cologne in Germany; 1992-1997: Physicist at the Brookhaven National Laboratory in Upton, New York; 1997-2004: Senior Research Scientist at the Wright Nuclear Structure Laboratory, Yale University, New Haven, Connecticut, USA. After the outstanding career abroad, Professor Zamfir return to the country and in 2004 became the General Director of the IFIN-HH, at the present holding the same position. Since 2012 Nicolae-Victor Zamfir is the Director of Extreme Light Infrastructure - Nuclear Physics (ELI-NP), a major European Infrastructure project, part of the Roadmap of the European Strategic Forum for Research Infrastructure (ESFRI). Research activity conducted by Professor Zamfir has spanned a wide range of topics in Nuclear Physics, Nuclear structure and Gamma-ray spectroscopy, being published in over 300 articles, with more than 5,000 citations and presented at more than 200 invited lecturers and contributions at International Conferences. Synergistic Activities: president of the Romanian Physical Society (since 2009) and the Romanian representative at CERN (since 2009), vice-chair of FAIR Scientific Council (2011-2015) and, starting with 2016, member of the Board of Directors of the Romanian – U.S. Fulbright Commission and member of the European Physical Society Executive Board, referee for Physical Review Letters, Physical Review C, Physics Letters B, Nuclear Physics A, International Journey of Modern Physics and Journal of Physics G. Member of four Editorial Board Physics Journals and of more than 30 Advisory Committees for various International Conferences, as well as member of Programme Advisory Committees of various research facilities, co-organizer of more than 20 International Conferences, Workshops and Summer Schools in Nuclear Physics, co-editor of eight Proceedings of International Conferences.

Plenary Lecture:          Nuclear and Laser Engineering – Component of Physics Research.

Abstract: Aspects of nuclear and laser engineering contribution to physics research at ‘Horia Hulubei” National Institute of Physics and Nuclear Engineering (IFIN-HH) and at the new international center for scientific research Extreme Light Infrastructure – Nuclear Physics (ELI-NP), Bucharest – Magurele, Romania, will be presented.

 

AlexandruAlexandru Stancu graduated the Faculty of Physics with Honors in 1980, the master degree in Optics, spectroscopy and plasma physics in 1981 and the PhD in physics (magnetism) in 1995, all at the “Alexandru Ioan Cuza” University in Iasi. He currently is a Professor at the Faculty of Physics, “Alexandru Ioan Cuza” University, ROMANIA and the Director of the Centre of Applied Research in Physics and Advanced TecHnologies (CARPATH) which is organized within the University. He is also the Director of the Integrated Platform for Advanced Studies in Molecular Nanotechnologies (AMON). He was Head of Department between 2000 and 2006 (Electricity and Physical Electronics 2000-2004, Solid State and Theoretical Physics 2004-2006). He is currently the Chair of the Romanian IEEE Magnetics Society, a Senior IEEE member and was member in the Administrative, Technical and in the Educational Committees of IEEE Magnetics Society. He is the Editor for the journal IEEE Magnetics Letters. He was keynote or invited speaker for many national and international conferences. He was invited professor in France, USA, Japan and Taiwan. He co-authored more than 300 ISI papers with more than 2000 independent citations in the domains of magnetism, hysteresis theory, and magnetization processes modelling. He is Knight of the Order “Merit in Education” in 2004 (Romanian Ministry of Education) and received in 2010 the “Stefan Procopiu” Award from the National Romanian Academy. His main scientific interest is on magnetism and magnetic materials. He is internationally recognized for the results he obtained in the study of non-linear physical processes with hysteresis in magnetic, ferroelectric and other types of materials. He contributed significantly to the development of the Preisach modelling and to the profound understanding of the physical basis of the phenomenological models of hysteresis.

Plenary Lecture:          First-order Reversal Curves (FORC) Diagram Characterization Technique of Hysteretic Processes

Abstract: One of the most significant contributions to the development of characterization techniques in magnetism is based on the measurement of a special category of minor loops known as first-order reversal curves (FORC) instead of the well-known use of the data from the major hysteresis loop. Typically, 100 FORCs that cover the surface of the major hysteresis loop are sufficient to produce an experimental FORC diagram. This diagram was for many years seen as a sort of magnetic sample fingerprint and was used to identify various phases present in the magnetic materials. This initial success was the fundament for the effort to transform the method from a virtually qualitative one to a powerful quantitative tool able to identify not only the presence of different phases but also to give information about the distribution of the coercive fields and of the intensity of interactions between the ferromagnetic particles/domains. The method was recently applied in other fields of physics and gradually became the standard characterization tool of hysteretic processes observed in ferroelectricity, geology, archeology, spin-transition materials, etc. The main research effort in the last few years is focused on the developing of the tools to improve the strength of the FORC diagram technique as a quantitative one able to provide a wealth of physical information in various technological problems. The talk will present the state-of-the-art in the FORC technique and the main recent developments in this area.
