WebWe confirm that the Curie temperature raising under electron doping is an intrinsic effect. A tiny electron doping reduces the magnetic frustration, resulting in a significant increase of the Curie temperature. We also calculate the spin-wave dispersion, and find a small spin gap as well as a nearly flat band in the magnon spectra.

WebOverview Abstract Magnons or spin waves occur in magnetic materials. A spin wave is a vibration in the magnetic property of the material: The magnetic north- and southpole of the atoms in a magnet are not fixed in place, but can vibrate about their equilibrium position.
Web9 apr. 2024 · "But in order to use spin waves to process quantum information, you need a mixed spin wave state." "Normally two magnon modes cannot generate a mixed spin state due to their different symmetries," Sun says. "But by harnessing the DMI we discovered a hybrid perovskite with a mixed magnon state." Sun is also a corresponding author of the …
