Pressure Effect on the Curie Temperature of Dy sub 2 Fesub(17-Y)Alsub(Y) Compounds

摘要

The pressure variation of the Curie temperature Tsub(c) has been measured up to 15 K-bar by means of the ac susceptibility. The pressure changes of Tsub(c) are negative, large and not linear, the Tsub(c)(p) curves being concave. The initial values of dTsub(c)/dp are remarkably large, being equal to -6.0 Kk-bar exp -1 for Dy sub 2 Fe sub 17 . (Atomindex citation 16:020534)
