title: Stabilization of antiferromagnetism in CeFe(2) alloys: the effects of chemical and hydrostatic pressure.
abstract: Effects of Al, Mn and Sb dopings in CeFe(2) 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.
