A new method for controlling the direction and intensity of the propagation of exchange spin waves by their managed refraction in inhomogeneous ferromagnetic structures such as spin lenses. The characteristics of the field and frequency dependences of the refractive indices of the respective branches of spin waves and focal length of spin lenses created on the basis of biaxial ferromagnet in an external constant magnetic field are obtained. The possibility of adjusting the transparency of such irregularities is shown. Product Description popup.authors Бруква О.М. Верба Р.В. Горобець О.Ю. Двойненко О.К. Захарченко В.Н. Куліш В.В.
