Antiferromagnetic Exchange Interactions in Ni_{2}Mn_{1.4}In_{0.6} ferromagnetic Heusler alloy

Magnetism in Ni-Mn-Z (Z = Ga,In,Sn,Sb) Heusler alloys has so far been predominantly attributed to Rudermann-Kittel-Kasuya-Yoshida type interactions between Mn atoms. We investigate magnetic interactions in one such alloy, Ni_{2}Mn_{1.4}In_{0.6} and attempt to explain the origin of antiferromagnetic (AFM) interactions that coexist with ferromagnetic ones. Through the combination of x-ray... Show more
