MAGNETIC AND RESISTIVITY INVESTIGATION OF DY(CO1-XSIX)(2) (0-LESS-THAN-X-LESS-THAN-OR-EQUAL-TO-0.2) COMPOUNDS

The results of experimental investigations of the magnetic and transpo rt (electrical resistivity) properties of Dy(Co1-xSix)(2), where x = 0 .0, 0.1 and 0.2 compounds are presented. These systems crystallize in the whole concentration range of x, in the MgCu2 Laves-phase-type crys tal structure. The zero-field-cooled (ZFC) and field-cooled (FC) magne tization measurements were performed on the pseudobinary Dy(Co1-xSix)( 2) cubic compounds. The thermomagnetic cycle of ZFC and FC processes e xhibits an irreversible behaviour. The composition dependence of the C urie temperature, 3d-magnetic moment and electrical resistivity is dis cussed. (C) 1997 Elsevier Science B.V. All rights reserved.
