A simple nonlinear model is proposed in this paper to study the solitary wave in a circular magneto-electro-elastic rod. Based on the constitutive relation for transversely isotropic piezoelectric and piezomagnetic materials, combined with the differential equations of motion, we derive the longitudinal wave motion equation in a long circular rod. The nonlinearity considered is geometrically as...

A low Gilbert damping factor is crucial for emerging magneto-acoustic devices. In current work, angle-dependent and temperature-dependent of magnetostrictive FeCoSiB thin films have been investigated using electron spin resonance (ESR) vector network analyzer ferromagnetic (VNA-FMR) techniques, respectively. very ∼0.0038 was measured with in-plane magnetic fields at room temperature. Temperatur...
