Raman phonons in multiferroic FeVO_4 crystals被引量:1
《Chinese Physics B》2015年第12期198-202,共5页张安民 刘凯 籍建葶 何长振 田勇 金峰 张清明 
Project supported by the National Basic Research Program of China(Grant No.2012CB921701);the National Natural Science Foundation of China(Grant Nos.11174367 and 11004243);the China Postdoctoral Science Foundation;the Fundamental Research Funds for the Central Universities;the Research Funds of Renmin University of China(Grant Nos.10XNI038;14XNLF06;and 14XNLQ03)
Multiferroic materials are promising candidates for next-generation multi-functional devices, because of the coexistence of multi-orders and the coupling between the orders. FeVO4 has been confirmed to be a multiferro...
