Temperature dependence of the spontaneous magnetization of Ni2MnGa and other ferromagnets. The superellipse equation
This paper proposes that the temperature dependence of spontaneous magnetization for Ni2MnGa and other ferromagnets can be fully described across the entire temperature range by a symmetric superellipse equation using only the Curie temperature and a single dimensionless critical exponent, thereby allowing the behavior near the Curie point to be predicted from low-temperature measurements.
