Magnetic domains in martensite of the Ni-Mn-Ga alloy
Tóm tắt
Structural changes that accompany an intermartensitic transformation in the Ni-Mn-Ga alloy have been considered. The magnetic domain structure of martensite in this alloy has been also studied with the help of optical microscopy using indicator films of iron garnet. A labyrinthine domain structure has been detected.
