Tunable dispersion relations manipulated by strain in skyrmion-based magnonic crystals We theoretically investigate the propagation characteristics of spin waves in skyrmion-based magnonic crystals. It is found that the dispersion relation ca... 金兆年,何宣霖,于超,... - 《Chinese Physics B》 被引...
Here, we provide unambiguous experimental evidence for braids of skyrmion strings in cubic crystals of chiral magnets. Magnetic skyrmions7,8,9,10 have been observed over a wide range of temperatures and applied magnetic fields in Ge-based and Si-based alloys with B20-type crystal structures, such...
(X07DA) beamline of the Swiss Light Source. Brillouin light scattering study in submicron LEGION based type of magnonic topology was supported by Russian Science Foundation (No. 18-79-00198). S.A.N. acknowledges support by the Government of the Russian Federation (Agreement No. 074-02-2018-...
Single crystals of FeGe were grown by the chemical vapour transport technique. Two grams of prepared FeGe powder and 2 mg/cc of the iodine transporting agent were used for the growth, with the source maintained at 450 °C and a temperature gradient of 50 °C across the length of ...
Note that the wave excited is just an ordinary mode expected for a tubular geometry, which does not assume the effect of magnonic activity. Depending on the skyrmion polarity, the transmitted wave becomes either a pure L or R mode, shown in Figure 7a and Figure 7b, respectively. Figure 7....
