Abstract

The temperature dependencies of the resistivity and magnetization of a series of Ni2+xMn1-xGa (x = 0-0.09) alloys were investigated. Along with the anomalies associated with ferromagnetic and martensitic transitions, well-defined anomalies were observed at the temperature of premartensitic transformation. The premartensitic phase existing over the temperature range 200-260 K in the stoichiometric Ni2MnGa is progressively suppressed by the martensitic phase with increasing Ni content and has vanished in the Ni2.09Mn0.91Ga composition.
