摘要
A He-gas compressor system is used to determine the dependence of the Curie temperature T-C of polycrystalline GdAgMg, EuAgMg, and EuAuMg and the Neel temperature T-N of GdAuMg on hydrostatic pressure to 0.8 GPa. The partial derivative T-C,T-N/partial derivative P dependences found differ significantly from those estimated from earlier thermal expansion studies on the same samples. Only for GdAgMg does the magnetic ordering temperature decrease with pressure.
