Strongly enhanced lifetime of higher-order bimerons and antibimerons

Changsheng Song, Dongzhe Li, Moritz A. Goerzen, Shiwei Zhu, Stefan Heinze

In a van der Waals interface, high-Q bimerons and antibimerons live up to three orders of magnitude longer than |Q|=1 versions even at room temperature.

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

We show that the lifetimes of high-Q (anti)bimerons can exceed the lifetime of those with |Q|=1 by 3 orders of magnitude. Remarkably, this trend remains valid even when extrapolated to room temperature (RT), as the lifetimes are dominated by entropy rather than energy barriers. This contrasts with high-Q skyrmions, whose lifetimes fall with |Q| near RT.

C2weakest assumption

The lifetime calculations and room-temperature extrapolation rest on the assumption that the chosen atomistic or micromagnetic model of the Fe3GeTe2/Cr2Ge2Te6 interface plus the entropy estimation method (likely transition-state or rate theory) accurately capture the Q-dependent fluctuation spectrum without post-hoc adjustments that alter the reported stability ordering.

C3one line summary

High-Q bimerons in Fe3GeTe2/Cr2Ge2Te6 show lifetimes three orders of magnitude longer than |Q|=1 bimerons at room temperature because entropy dominates decay rates.
