        abstract = {The Tb(Fe0.55Co0.45)1.5 films were fabricated by rf magnetron sputtering from a composite target. Samples were investigated by means of x-ray diffraction, vibrating sample magnetometer, conversion electron M{\"o}ssbauer spectra, and magnetostriction measurements. The as-deposited film is an amorphous alloy with a perpendicular magnetic anisotropy and an intrinsic magnetostriction {\ensuremath{\lambda}}=1080{$\times$}10-6 in an applied field of 0.7 T. In this state, it was determined that the hyperfine field Bhf=23.5 T and the cone-angle between the Fe moment direction and the film-normal direction {\ensuremath{\beta}}=12?. After annealing in the temperature range of TA=250?450 ?C the amorphous structure still remained, however the anisotropy was changed to a parallel one. The soft magnetostrictive behavior has also been improved by these heat treatments: the parallel magnetostriction {\ensuremath{\lambda}}{\ensuremath{|}}{\ensuremath{|}}=465{$\times$}10-6 was almost developed in low applied fields of less than 0.1 T and, especially, a huge magnetostrictive susceptibility {\ensuremath{\chi}}{\ensuremath{\lambda}}=d{\ensuremath{\lambda}}{\ensuremath{|}}{\ensuremath{|}}/d({\ensuremath{\mu}}0H)=1.8{$\times$}10-2 T-1 was obtained at {\ensuremath{\mu}}0H=15 mT. {\copyright} 2000 American Institute of Physics.}
