Mach-Zehnder Interferometer for spin waves: computing applications
Kirill A. Rivkin
Interferometers are some of the most important optical devices, yet their spin wave based analogues so far received limited attention. In this work we demonstrate how one can desig…

Spin Wave Optics
Kirill A. Rivkin
We propose a mathematical apparatus which converts magnetostatic (Walker) equations into a wave equation by introducing a specific definition of the magnetic refractive index. Its…

Continuous Neel to Bloch Transition as Thickness Increases: Statics and Dynamics
Kirill Rivkin, Konstantin Romanov, Yury Adamov +3
We analyze the properties of Neel and Bloch domain walls as a function of film thickness h, for systems where, in addition to exchange, the dipole-dipole interaction must be includ…
