Topol. spin textures such as skyrmions hold high potential for use as magnetically active elements in diverse near-future applications. While skyrmions in metallic multilayers attract great attention in this context, unleashing the myriad potential of skyrmions for various applications requires the discovery and customization of alternative host system paradigms. Here, we developed and applied a chem. method to synthesize octahedral particles of the chiral insulating skyrmion host Cu2OSeO3 with both narrow size distribution and tailored dimensions approaching the nanoscale. Combining magnetometry and neutron scattering experiments with micromagnetic simulations, we show that the bulk phase diagram of Cu2OSeO3 changes dramatically below octahedral heights of 400 nm. Further, particle size-dependent regimes are identified where various topol. spin textures such as skyrmions, merons, and bobbers can stabilize, prior to a lower critical octahedral height of 1̃90 nm below which no topol. spin texture is found stable. These findings suggest conditions under which sparse topol. spin textures confined to chiral magnet nanoparticles can be stable and provide fresh potential for insulator-based application paradigms. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2SDS of cas: 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents has turned up as an exceedingly robust synthetic tool. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.SDS of cas: 20427-59-2
