Single- and oligo-crystalline magnetic shape memory (MSM) Ni45.2Mn36.7In13Co5.1 particles were prepared by mechanical grinding the melt-spun ribbons. The influence of annealing and grinding on the crystal structure and magnetic properties of the ribbons and particles was systematically investigated. The obtained Ni45.2Mn36.7In13Co5.1 single-crystalline particles exhibit a field-induced martensitic transformation above room temperature, thus are used for MSM-polyester composites.
