Abstract
Giant magnetostriction has been obtained in Tb 0.36Dy 0.64(Fe 1− x T 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 0.64Fe 2, 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− x T 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.
