Abstract

Giant magnetostriction has been obtained in Tb_0.36Dy_0.64(Fe_1-xT_x)₂ (T = Mn or Co) alloys over a wide temperature range from -80 to 100 °C. The results show that Co or Mn substituting for Fe can extend the operating temperature range for Tb_0.36Dy_0.64Fe₂, due to the increase of Curie temperature T_c or the decrease of spin reorientation temperature T_r, respectively. In addition, the substitution of Co or Mn can partly compensate the magnetocrystalline anisotropy enlarged by increasing Tb/Dy ratio 〈1 1 0〉 and 〈1 1 2〉 grain-aligned rods of Tb_0.36Dy_0.64(Fe_1-xT_x)₂ alloys have been successfully prepared. Giant magnetostriction higher than 1450 ppm has been obtained in the oriented Tb_0.36Dy_0.64(Fe_0.70Co_0.30)₂ rod in 3 kOe magnetic field under 10 MPa pre-stress at room temperature, and can be kept over a wide temperature range from -80 to 100 °C.
