Abstract: 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.<br />Funding Agencies|National Science FoundationNational Science Foundation (NSF) [NSF/DMR-1644779]; State of Florida; PAZY foundation; Knut and Alice Wallenberg (KAW) FoundationKnut & Alice Wallenberg Foundation; Swedish Research CouncilSwedish Research Council [642-2013-8020]
