Microscopic evidence for Mn-induced long range magnetic ordering in MAX phase compounds

• Zero and low field nuclear magnetic resonance measurements have been performed on MAX phase samples (Cr1-xMnx)(2)AC withA= 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 (Cr0.96Mn0.04)(2)GeC and for (Cr0.93Mn0.07)(2)GaC, but not for (Cr0.97Mn0.03)(2)GaC. We point to a possible dependence of long range magnetic order in these MAX phase compounds on theAatom.
