邀请讲座人：Lluís Mañosa 教授
简介：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 Institute des Sciences Appliquées (INSA, Lyon, France) and at University of Bath (UK), and he was a 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 Materials, Nature Communications, Advanced Materials, etc. and has served as organizer or co-organizer of various international conferences and symposia.
【报告题目】Multicaloric materials and effects
时间: 10:00-11:00 am, May 16th, 2018
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.
