Abstract

Abstract: Zero and low field nuclear magnetic resonance measurements have been performed on MAX phase samples (Cr1− x Mn x )2 AC with A = Ge and Ga in order to obtain local microscopic information on the nature of magnetism in this system. Our results unambiguously provide evidence for the existence of long-range magnetic order in (Cr0.96 Mn0.04 )2 GeC and for (Cr0.93 Mn0.07 )2 GaC, but not for (Cr0.97 Mn0.03 )2 GaC. We point to a possible dependence of long range magnetic order in these MAX phase compounds on the A atom.
