Large Non-ergodic Magnetoelastic Damping in Ni-Mn-Ga Austenite
Original language description
Resonant ultrasound spectroscopy was used to analyze magnetoelastic damping in Ni-Mn-Ga single crystals in austenite and premartensite phases. Crystals with different treatment were studied, exhibiting different density of antiphase boundaries (APBs), as confirmed by magnetic force microscopy, and different magnetic behavior. For a quenched single crystal with high density of APBs, extremely strong damping was observed in a broad temperature range in the austenite phase. It was shown that this damping is history-dependent, i.e., non-ergodic, appearing only during heating runs preceded by a premartensite-austenite transition.
