Abstract [en]

Bi(0.9)Ho(0.1)FeO(3) ceramic is prepared by sol-gel method. We investigated the effect of Ho element doping in the BiFeO(3). We studied the microstructure, morphology and ferromagnetism for Bi(0.9)Ho(0.1)FeO(3) ceramic by XRD, SEM and SQUID. It shows that Bi(0.9)Ho(0.1)FeO(3) ceramic exhibits single phase of perovskite structure. The c/a rate is elevated from 1 to 1.009 with respect to BiFeO(3). The grains of Bi(0.9)Ho(0.1)FeO(3) ceramic shrink sharply compared with the ones of BiFeO(3) ceramic, which is beneficial to the connection between grains and the density. Bi(0.9)Ho(0.1)FeO(3) ceramic exhibits obvious ferromagnetism while BiFeO(3) ceramic does not possess the macroscopic ferromagnetism at the RT. The magnetization sinks in the horizontal direction near the zero magnetic field. It indicates that Bi(0.9)Ho(0.1)FeO(3) ceramics do not only show obvious ferromagnetism, but also could exhibit lower magnetic hysteresis loss.
