Abstract:

Magnetism and magnetic materials have a long history that begins in antiquity. Knowledge in the field went in-depth with the applications of magnetic materials in the so-called industrial revolution. Theories and modeling of magnetization processes have evolved continuously. Current scientific research in the field is confronted with the challenges of miniaturization of electronic devices, sensors and actuators that are nanometer-sized. The behavior of magnetic materials depends on the chemical composition, size and structural characteristics. The lecture will highlight, through successive and relevant comparisons, the role played by the magnetic domains dimensions in establishing possible technological and medical applications. Nanomagnetism will be addressed in the end.

Ovidiu Florin Caltun

CALTUN Ovidiu Florin received his Ph.D. in 1998 at Faculty of Physics, Alexandru Ioan Cuza University, Iasi, Romania defending the thesis “Magnetic and Electrical Properties of Bismuth Doped Manganese Zinc Ferrite”. He was fellow researcher in Taiwan at University of Changhua working in pulsed laser deposition (PLD) of thin ferrite films, DAAD Fellow at Saarland University Germany and Fulbright Scholar at Polytechnic State University San Luis Obispo California US working in STEM Education. From 2009 he is full professor at Faculty of Physics, Alexandru Ioan Cuza University of Iasi, Romania and is leading the Laboratory of Magnetic Materials for Technological Applications LMAT. He has published more than 200 papers in Material Science and Science Education. More than 100 are in ISI journals with a Hirsch index of 24. The main research interests are in nanoparticles for medical applications, thin films for sensors applications and multiferroics. In STEM education, networking at international level, his contribution is highly recognized by published papers in proceedings and invited talks. He was invited for lectures in USA, France, Germany, Italy, Greece, Japan, Chile, Serbia, Albania, Poland, Slovakia, Lithuania, Estonia, Bulgaria, Cyprus, Portugal, Spain, and Taiwan. Currently he is serving as president of “Alliance of Educators for Science, Technology, Engineering, Mathematics and Informatics” ESTEEM Romania. He is member of IEEE Magnetics and Education Chapters, GIREP and EPS professional associations.
