A complete set of elastic constants Cij of an Fe79 Si12 B9 amorphous alloy free standing thin film has been determined by using ultrasound spectroscopy techniques. The out-of-plane shear moduli of C44 and C55 are measured by the thickness resonance frequencies and are almost elastic isotropic in the film plane indicating that the thin film has a hexagonal-type elastic symmetry. The remaining Cij in the symmetry are determined by the modified resonance ultrasound spectroscopy coupled with a laser-Doppler interferometory. Inverse calculation showed elastic anisotropies between the in-plane and the out-of-plane directions; C33 / C11 =1.21 and C66 / C44 =1.26. Magnetic property measurements also revealed the remarkable magnetization difference between the two directions suggesting that the structural difference between the in-plane and the out-of-plane directions would be responsible for them. © 2007 American Institute of Physics.
