Nanoconstriction spin-Hall oscillator with perpendicular magnetic anisotropy
B. Divinskiy, V. E. Demidov, A. Kozhanov +3
We experimentally study spin-Hall nano-oscillators based on [Co/Ni] multilayers with perpendicular magnetic anisotropy. We show that these devices are capable of single-frequency a…
Efficient geometrical control of spin waves in microscopic YIG waveguides
S. R. Lake, B. Divinskiy, G. Schmidt +2
We study experimentally and by micromagnetic simulations the propagation of spin waves in 100-nm thick YIG waveguides, where the width linearly decreases from 2 to 0.5 micrometers…
Dispersionless propagation of ultra-short spin-wave pulses in ultrathin yttrium iron garnet waveguides
B. Divinskiy, H. Merbouche, K. O. Nikolaev +10
We study experimentally the propagation of nanosecond spin-wave pulses in microscopic waveguides made of nanometer-thick yttrium iron garnet films. For these studies, we use micro-…
Controllable excitation of quasi-linear and bullet modes in a spin-Hall nano-oscillator
B. Divinskiy, V. E. Demidov, S. Urazhdin +3
We experimentally demonstrate that both quasi-linear and nonlinear self-localized bullet modes of magnetization auto-oscillation can be excited by dc current in the nano-gap spin H…
Effects of spin-orbit torque on the ferromagnetic and exchange spin wave modes in ferrimagnetic CoGd alloy
B. Divinskiy, G. Chen, S. Urazhdin +2
We use micro-focus Brillouin light scattering spectroscopy to study the effects of spin-orbit torque on thermal spin waves in almost angular-momentum compensated ferrimagnetic CoGd…
Direct evidence of spatial stability of Bose-Einstein condensate of magnons
I. V. Borisenko, B. Divinskiy, V. E. Demidov +4
Bose-Einstein condensation of quasi-equilibrium magnons is one of few macroscopic quantum phenomena observed at room temperature. Since its discovery, it became an object of intens…
