The study for ferromagnetic properties and microstructure of Bi0.9Ho0.1FeO3

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.
