The prospects of nonthermal magnetization switching in near-compensated rare earth iron garnets

A. K. Zvezdin, D. O. Ignatyeva, N. A. Gusev, N. I. Gribova, V. I. Belotelov

Femtosecond laser pulses can deterministically switch the magnetization in near-compensated rare earth iron garnets via the inverse Faraday effect above a threshold intensity.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The results demonstrate a clear threshold behavior: weak pulses induce only oscillations around the initial equilibrium state, while a stronger excitation results in a deterministic magnetization switching. The switching threshold is determined by the magnetic state of the sample on its phase diagramme as well as on the laser pulse helicity.

C2weakest assumption

The model assumes that the inverse Faraday effect can be treated as a purely non-absorptive effective magnetic field acting on the Néel vector, with no significant thermal or absorptive contributions that would alter the effective potential landscape during the pulse.

C3one line summary

Numerical simulations of Néel vector dynamics reveal a helicity- and state-dependent threshold for nonthermal deterministic magnetization switching in near-compensated rare earth iron garnets.
