| Abstract: | The hexagonal BaLa x Fe 12- x O 12 ,BaNd x Fe 12- x O 12 ,BaSm x Fe 12- x O 12 ,BaGd x Fe 12- x O 12 ultrafine powders with M type structure were synthesized by sol gel self propagating high temperature synthesis technique. The effect of different kinds of rare earth, different amount of rare earth, different synthesis conditions on ultrafine powders' magnetic properties was discussed systematically. Their magnetic properties were measured by means of vibrating sample magnetometer. |
