A μSR study of the magnetic ground state of Ni3Al

Kilcoyne, SH; Cywinski, R

Abstract

The magnetic ground state of a well-characterised and highly ordered Ni3Al sample has been studied by muon spin relaxation. Although it is widely accepted that Ni3Al is an archetypal homogeneous weak itinerant electron ferromagnet with a Curie temperature of 40 K, our μSR measurements provide no evidence of long-range magnetic order, but instead indicate the evolution of an inhomogeneous magnetic ground state at temperatures below 40 K in which relatively static magnetic clusters coexist with a spin fluctuating state.
