Abstract:
Magneto-optical spectra of polycrystalline samples of the Fe$_{48}$Mn$_{24}$Ga$_{28}$ Heusler alloy undergoing martensitic transformation from the high-temperature paramagnetic austenitic to ferromagnetic martensitic phase have been studied at 50–320 K in the transversal Kerr effect geometry. A comparison of magnetooptical spectra with data obtained in magnetic measurements has demonstrated that the martensitic transition on the surface of a sample and in its bulk takes place in the same temperature interval. Magnetic anisotropy has been found in the martensitic phase driven by large multidomain inclusions of martensite in austenite. The magneto-optical signal of Fe$_{48}$Mn$_{24}$Ga$_{28}$ differs strongly in spectral shape from that measured in Ni–Mn–Ga.
