Equivalence of mechanical and magnetic force in magnetic shape memory effect
Original language description
High mobility of twin boundary is crucial for magnetic shape memory (MSM) effect. The twin boundary can be moved by applied magnetic field or mechanical stress. In Ni-Mn-Ga 10M martensite there are two different, field-movable, a-c twin boundaries Type Iand II due to monoclinic lattice. For single twin boundary of both types we experimentally evaluated the equivalence of magnetic and mechanical force and the validity of generally used energy model using direct stress-strain and magnetization measurements. For Type II, highly mobile twin boundary, the equivalence seems to be valid and model broadly agrees with measurement. However, for Type I the calculated magnetic stress is much larger than mechanical stress needed for twin boundary motion.
