摘要：

The deformations of a bimorph, consisting of a non-magnetic substrate and a magnetic thin film, under the influence of (i) an isotropic stress, e.g. due to thermal expansion and (ii) a uniaxial magnetic field (Joule magnetostriction) have been derived: the formula proposed by Klokholm in 1976 and widely accepted until now predicts magnetostrictive strains about twice as large as the ones actually observed. The corrected formula takes into account the anisotropic character of the Joule magnetostriction. The conditions of validity of this formula are discussed.
