报告摘要/Abstract:

Multicaloric materials show thermal changes that can be driven simultaneously or sequentially by more than one type of external field. The use of more than one driving field can induce larger thermal changes, with smaller field magnitudes, over wider ranges of operating temperature, and can also eliminate hysteresis in one control parameter by transferring it to another. In my talk I will describe the fundamentals of multicaloric effects and discuss the performance of representative multicaloric materials.

报告人简介/Brief introduction of speaker:

Lluis Mañosa is Professor of Condensed Matter Physics at the Universitat de Barcelona (Catalonia). He received his BSc in Physics at the University of Barcelona (Catalonia), and his PhD in Physics from the same University. He carried out post-doctoral stays at Institut des Sciences Appliquées (INSA, Lyon, France) and at University of Bath (UK), and he was visiting professor at Ames Laboratory (Iowa, US). His research is devoted to the study of thermal, mechanical and magnetic properties of solids undergoing ferroic phase transitions. His current research focuses on materials exhibiting functional properties associated with these transitions, with a special attention paid to the interplay between different ferroic properties. Presently he is particularly centered in materials displaying giant caloric and multicaloric properties. He has authored and co-authored over 200 publications, including books, reviews and tens of high-impact papers published in Nature MaterialsNature CommunicationsAdvanced Materials, etc. and has served as organizer or co-organizer of various international conferences and symposia.
