摘      要： oriented Tb0.27Dy0.73Fe1.95 alloys were studied under different applied compressive *** saturation magnetostriction by 500×10-6 is obtained for the sample under 5 MPa than that under no applied *** understand the effect of prestress on the magnetostrictive coefficient,differential magnetostrictive coefficient,relative permeability and coercive force were studied in *** results show that the maximum differential magnetostrictive coefficient is about 37 x 10-9 m·A-1,about two times that without *** addition,the saturation magnetostriction coefficient increases gradually with the stress increasing,while the maximum differential magnetostrictive coefficient *** saturation inductions under different stresses are similar to a value of about 1.1 *** relative permeability decreases with stress increasing.
