Abstract

The pressure response of CeAg1−xNixSb2 is studied by means of electrical resistivity measurements. The ferromagnetic ordering temperatures TC of this series decrease as pressure is applied, except CeNiSb2, showing a pressure driven continuous increase of TC. This refers to crystalline electric field effects originating distinct different magnetic ground states. Concomitantly, the pressure response of various material dependent parameters also behave in the opposite direction..
