Effect of Hydrostatic Pressure on the Magnetic Transition Temperature of GdAg_1−xIn_x Compounds

抄録

Change in the Néel temperature and the Curie temperature of the compound system GdAg_1−xIn_x with hydrostatic pressure has been measured up to 6 kbar by means of a standard Hartshorn bridge circuit. The Néel temperature does not change with pressure within an experimental error. The Curie temperature shifts to the higher temperature with increasing pressure. The value of pressure derivative ΔT_C⁄Δp increases with increasing x. The results obtained are discussed on the basis of the indirect exchange theory.
