Figure 1: Spin excitations via microwave in the multiferroics Cu₂OSeO₃.

From: Microwave magnetoelectric effect via skyrmion resonance modes in a helimagnetic multiferroic

(a) Magnetic phase diagram under H_dc|| determined by magnetic a.c. susceptibility measurement. The vertical line represents a change in scale. Inset illustrates the spin texture of a skyrmion. Each arrow represents the net magnetic moment. (b–d) Schematic illustration of skyrmion resonant motions: (b) CCW and (c) CW modes, where the core of skyrmion rotates in such a sense, and (d) a breathing mode, where the skyrmion oscillatingly shrinks and enlarges.
