Abstract: Understanding the spin-wave excitations of chiral magnetic order, such as the skyrmion crystal (SkX), is of fundamental interest to confirm such exotic magnetic order. The SkX is realized by competing Dzyaloshinskii-Moriya and ferromagnetic-exchange interactions with… read more here.

DOI: 10.1103/physrevb.95.224406
Abstract: The collective spin-wave excitations in the antiferromagnetic state of $\gamma$-Fe$_{0.7}$Mn$_{0.3}$ were investigated using the inelastic neutron scattering technique. The spin excitations remain isotropic up to the high excitation energy, ${\hbar\omega}= 78$ meV. The excitations gradually… read more here.

DOI: 10.1103/physrevb.97.064418
Abstract: We study azimuthal spin-wave (SW) excitations in a circular ferromagnetic nanodot in different inhomogeneous, topologically non-trivial magnetization states, specifically, vortex, Bloch-type skyrmion and N\'eel-type skyrmion states. Continuous mapping of the SW spectrum between these states… read more here.

DOI: 10.1103/physrevlett.118.107203
Abstract: Kitaev interactions underlying a quantum spin liquid have long been sought, but experimental data from which their strengths can be determined directly, are still lacking. Here, by carrying out inelastic neutron scattering measurements on high-quality… read more here.

DOI: 10.1134/s1063783419090257
Abstract: In this paper, we study the features of the spin-wave excitation spectrum in a YIG film with a thickness of 0.4 μm and a magnetization of 1.1 kG corrugated due to the periodic relief of… read more here.
