摘要：

Results of magnetovolume studies are presented on intermetallic compounds and binary alloys with weakly ferromagnetic properties of the following compositions: Ni3Al, (Ni, Fe)3Ga, Ti(Fe, Co), (Ti, Al)Co, Ni-Pt and Pd-Ni. Data for the pressure dependence of the spontaneous magnetization at 4.2 K and the shift of the Curie temperature with pressure follow roughly the realtions that can be derived in the model for weak itinerant ferromagnetism in most of the investigated systems. Invar-type of anomalies in the thermal expansion have already been observed in several cases. Experimental values for the magnetovolume parameter are derived and compared with theoretical predictions in the Stoner model. © 1979.
