Low-temperature properties of the Ce(Pd $\mathsf{_{1-x}}$ Ni $\mathsf{_{x})_{3}}$ system

Abstract

The influence of substituting Pd by Ni is described in Ce(Pd1-x Ni x )3 alloys with x taken up to about 0.25. Thermal and magnetization measurements point out a transition from a non-magnetic state (CePd3) to a ferromagnetic state for x > 0.05, with a Curie temperature T c ≈ 2 K. The Ce-L 2,3 absorption edges and magnetic circular dichroism (XMCD) study reveals the coexistence of strong 4f hybridization and ferromagnetic order. The Ce-L 2,3 XMCD signal measured in CePd3 demonstrates that in the Ce-based dense Kondo materials only the 4f 1 channel gives a magnetic response.
