Elastic dipole mechanism of the formation and collapse of Fano resonances at the transmission of transverse phonons through layered magnetic heterostructures

At the resonant passage of a plane elastic shear wave through an acoustically continuous heterostructure consisting of magnetic and nonmagnetic layers in a symmetric nonmagnetic environment, the excitation of propagating exchangeless and exchange spin waves can lead to the formation of elastodipole analog of the Fano resonance and accompanying dynamic effects, including the collapse of the Fano resonance and the appearance of coupled magnon states in the continuum of transverse phonons.
