Element-specific magnetic properties of compensated ferrimagnet Mn2Co1-xVxAl Heusler alloy films

[摘要] We fabricated compensated ferrimagnet Heusler alloy Mn2Co1-xVxAl films and investigated composition dependence of macroscopic magnetic properties with detailed microscopic magnetism probed by X-ray magnetic circular dichroism. The compensation of magnetization at x = 0.5 was observed even in the thin film case. With increasing V concentration, the exchange coupling becomes antiferromagnetic among the V-Mn-Co sites. We found that the origin of magnetization compensation mainly comes from the anti-parallel coupling within the each Mn and Co site for our films.
