“…In addition, a solution has been presented for plates with magnetoelastic interactions. 19,20 These calculations have taken account of a wide range of boundary conditions, including multilayer samples. [21][22][23] In experiments with the magnetization saturated, except in the immediate vicinity of the resonance, the imaginary part of the impedance is very small.…”

“…This is not surprising since Terfenol-D's unique magnetostrictive behavior will not be clearly exhibited in a reflection experiment unless the sample is extremely thin. 4,5 The magnetoelastic properties, however, figure prominently in a microwave transmission experiment. It is the purpose of this article to present calculations of the expected microwave transmission through Terfenol-D and to draw attention to the qualitative features that are due to the large magnetostriction.…”

The calculated transmission of microwave power at GHz frequencies through Terfenol-D (Tb0.27Dy0.73Fe2) is strongly influenced by the enormous magnetostriction parameter of this material. For conditions satisfying ferromagnetic resonance there is a peak in the transmission corresponding to sound and spin waves transporting energy through a slab-shaped sample. The magnetostriction mixes the character of these waves; the calculated transmission also depends on the exchange stiffness parameter, the elastic constants, and the radio-frequency magnetic properties. With thin (<40 μm) samples for which the static magnetization is along the magnetically soft (111) direction the calculated transmission peak is augmented by a fringe pattern with more than 20 secondary peaks. This arises from interference between spin and sound waves. For the configuration with the static magnetization oriented along the magnetically hard (100) direction the fringe pattern is absent. In this configuration the spin wave is a soft mode and the sample should develop a static distortion of the magnetization and lattice. The periodicity of this static distortion is tunable with an external magnetic field, although lattice imperfections may introduce hysteresis by pinning the distortion.

The magnetoelastic interaction energy of a cubic ferromagnet is expressed in a most general coordinate system, to facilitate the theoretical investigations of magnetoelastic wave propagation in ferromagnets, when the direction of magnetization relative to the cube edges is arbitrary. The coefficients of the various terms in the expression of the magnetoelastic interaction energy are tabulated. Some special cases are also discussed.
