A microwave absorption study in the ferromagnetoelectric Pb(Fe1-xMx)O3 (M= Ta,W, Nb) perovskites

We report on the effects of dc magnetic field and temperature on the microwave absorption measurements at X-band (8.8-9.8 GHz), in powder samples of perovskites Pb(Fe1=2Ta1=2)O3 (PFT), Pb(Fe1=2Nb1=2)O3 (PFN) and Pb(Fe2=3W1=3)O3 (PFW). At room temperature (300 K), in all these ferromagnetoelectric ma...
