Magnonic spontaneous oscillation induced by parametric pumping
Yi Li, Carissa Kiehl, Jinho Lim +10
Spontaneous dynamic systems have attracted significant attention for their rich underlying physics such as phase-locking and synchronization. In this work, we report a new mechanis…
Wave dynamics in a macroscopic square artificial spin ice
L. Scafuri, D. A. Bozhko, E. Iacocca
A macroscopic square artificial spin ice, or macro-ASI, is a collection of bar magnets placed in a square lattice arrangement. Each magnet is supported by hinges that allow their m…
Frequency comb in a macroscopic mechano-magnetic artificial spin ice
Renju R. Peroor, Lawrence Scafuri, Dmytro A. Bozhko +1
Artificial spin ices are metamaterials composed of interacting nanomagnets exhibiting frustration. Their resonant magnetization dynamics have been broadly investigated from fundame…

Nowadays, the interaction between phonon and magnon subsystems of a magnetic medium is a hot topic of research. The complexity of phonon and magnon spectra, the existence of both b…
Unconventional spin currents in magnetic films
Dmytro A. Bozhko, Halyna Yu. Musiienko-Shmarova, Vasyl S. Tiberkevich +4
A spin current - a flow of spin angular momentum - can be carried either by spin polarised free electrons or by magnons, the quanta of a moving collective oscillation of localised…
Microwave magnon damping in YIG films at millikelvin temperatures
Sandoko Kosen, Arjan F. van Loo, Dmytro A. Bozhko +2
Magnon systems used in quantum devices require low damping if coherence is to be maintained. The ferrimagnetic electrical insulator yttrium iron garnet (YIG) has low magnon damping…
