WebThe magnetization process is strongly dependent on the magnetostriction constant and the magnetoelastic anisotropy induced by internal stresses (Vázquez et al. 1996 ). Glass coating induces an extra radial internal stress due to the different thermal expansion coefficients of the nucleus and the glass.
