Magnetic order in Mn excess Ni-Mn-Ga Heusler alloy single crystal probed by ferromagnetic resonance

Popis výsledku v původním jazyce

Magnetic order and its changes upon martensitic transition are investigated in non-stochiometric Ni50Mn28Ga22 single crystal exhibiting magnetic shape memory effect by ferromagnetic resonance. The resonance is measured with magnetic field applied in plane along two 〈1 0 0〉 perpendicular directions in the flat rectangular sample. While for one field direction the spectrum can be explained by the standard ferromagnetic resonance, for the other the spectrum suggests the two sublattice model of ferrimagnetic resonance. Magnetic anisotropy of martensite, determined from the resonance fields, well corresponds with the magnetocrystalline anisotropy obtained by the static methods. On transition to the austenite phase magnetic anisotropy disappears while exchange resonance mode derived from the two sublattice model persists.
