N2 - To obtain a large strain of Ni-Fe-Ga-Co ferromagnetic shape memory alloys, the effects of Mn on the magnetocrystalline anisotropy constant Ku, and the magnetic-field-induced strain (MFIS) under static stresses were investigated. The value of Ku was increased by the addition of Mn, and Ni49.5Fe14.5Mn4.0Ga26.0Co 6.0 alloy was accompanied by a relatively large value of -1.5 × 105 J/m3 at room temperature. From the stress-strain curves of this alloy, the twinning stress is estimated to be 8-10 MPa. Consequently, the Ni49.5Fe14.5Mn4.0Ga 26.0Co6.0 alloy provides a large MFIS of about 11.3% at room temperature under a static compressive stress of about 8 MPa.
