Abstract
The pressure dependence of the crystal structure of a powder sample of Y2Fe 15.3Si1.7 was studied in the pressure range from 0 to 2 GPa, using the D-2 diffractometer with hydrostatic liquid pressure cell at the IVV-2M reactor (Ekaterinburg) and DN-12 time-of-flight diffractometer with a sapphire anvi l cell at the IBR-2 pulsed reactor (Dubna). Also the pressure dependence of the Curie temperature T-c(P) of the alloy was studied. The correlation bet ween the decreases of both T-c and Fe-Fe interatomic distances in "dumbbell " site 4f under pressure was obtained.
