Influence of three-dimensional transition elements on magnetic and structural phase transitions of Ni-Mn-Ga alloys

A. A. Cherechukin; T. Takagi; Hiroyuki Miki; Munehisa Matsumoto; Makoto Ohtsuka

Differential scanning calorimetry and magnetic measurements were performed to study the influence of the ferromagnetic three-dimensional transition elements Fe and Co on the structural and magnetic properties of the ferromagnetic shape memory alloys Ni-Mn-Ga. Substitution of Fe or Co for Ni decreases the temperature of martensitic phase transition Tm, whereas substitution of Co for Mn results in a considerable increase of Tm. Magnetic measurement revealed that Curie temperature TC increased upon substitution of Fe or Co for Ni. This may be useful for design of high-temperature ferromagnetic shape memory alloys.
