Abstract

Abstract In this work, we studied the magnetic properties of as-prepared and annealed Ni-Mn-Ga Heusler alloy glass-covered microwires. We observed that the annealing conditions strongly affect the magnetic field dependencies of magnetic moments, the temperature dependence of the magnetization, and the Curie temperature of microwires. By mixing the microwires annealed at different temperatures, we achieved the broadening of the second-order phase transition.
