Abstract

The temperature dependence of the electrical resistivity ρ of Ni2Mn1-xCrxGa (x=0.05∼0.25) was measured. Two anomalies corresponding to the magnetic and structural phase transitions at TC and TM were observed on the ρ-T curves for each sample, respectively. The kinks corresponding to the premartensitic transition at Tp were observed for all samples except x=0.25. On the basis of the experimental results, the T vs. x phase diagram of Ni2Mn1-xCrxGa was determined.
