2019 IEEE MAGNETICS SOCIETY DISTINGUISHED LECTURER
Magnetocaloric Effect: From Energy Efficient Refrigeration to Fundamental Studies of Phase Transitions
by Prof. Victorino Franco, University of Seville, Seville, Spain
Monday, 14 October 2019 @ 12 pm
ICMAB - Sala d'Actes MATGAS
I will cover an overview of the phenomenon and a classification of the most relevant families of alloys and compounds. I will analyze possible limitations for the optimal performance of the materials in magnetic refrigerators, including hysteretic response and cyclability. Regarding phase transitions, I will present a new method to quantitatively determine the order of thermomagnetic phase transitions using the field dependence of the magnetic entropy change. For second-order phase transition materials, I will show that critical exponents can be determined using the magnetocaloric effect even in cases where the usual methods are not applicable. In the case of first-order phase transitions, more details about their hysteretic response can be obtained using T-FORC.
Victorino Franco is a professor in the Condensed Matter Physics Department of the University of Seville, Spain. His main research interests cover magnetic materials for energy applications, including soft-magnetic and magnetocaloric materials. He has published more than 165 peer-reviewed technical articles. In 2000, he received the Young Scientist Award from the Royal Physical Society of Spain. He served as chair of the Spain Chapter of the IEEE Magnetics Society and chair of the Magnetic Materials Committee of the Minerals, Metals & Materials Society (TMS).
He has been editor and publications chair of several Magnetism and Magnetic Materials (MMM) conferences and will be the general chair of the 2022 Joint MMM-Intermag Conference.
