The concentration dependence of magnetic properties in the austenite phase of NiCoMnIn and NiCoMnSn Heusler alloys was systematically investigated by the magnetization measurements. The TC for Ni(50-x) Co x Mn(50-y) Sny alloys linearly increases with increasing the Co content and fixed Sn content. Although showing a concave curve for Ni50 Mn(50-y) Sny ternary alloys, the Sn content-dependence of magnetic moment per formula unit changes from the concave curve to a straight line when Co is substituted for Ni. On the other hand, the In content-dependence of the magnetic moment for Ni45 Co5 Mn(50-y) Iny alloys is perfectly linear as is that in the Ni50 Mn(50-y) Iny ternary alloys.
