Abstract
A ferromagnetic shape memory alloy comprising 25-50 atomic % of Mn, 5-18 atomic % in total of at least one metal selected from the group consisting of In, Sn and Sb, and 0.1-15 atomic % of Co and/or Fe, the balance being Ni and inevitable impurities, which has excellent shape memory characteristics in a practical temperature range, thereby recovering its shape by a magnetic change caused by a magnetic-field-induced reverse transformation in a practical temperature range.
