|Title:||Stabilization of antiferromagnetism in CeFe2 alloys: the effects of chemical and hydrostatic pressure|
|Abstract:||Effects of Al, Mn and Sb dopings in CeFe2 and the effect of applied pressure have been investigated. Al doping gives rise to the FM-AFM transition and a reduction in the magnetic moment and T-C values, clearly indicating the growth of the AFM component. Mn and Sb dopings only cause a reduction in the T-C value. It is found that, in general, external pressure enhances the antiferromagnetism in both the pure and the doped alloys. Enhancement of the Ce 4f-Fe 3d hybridization as a result of doping and with the external pressure may be the reason for the stabilization of antiferromagnetism in these alloys.|
