Abstract (in Japanese) (See Japanese page) 
(in English) Magnetic skyrmions, which are topologically protected whirling spin textures with nanometer-scale dimensions, have great potential for use in future data storage devices. Transition-metal monogermanides (TMGe) with a B20-type chiral structure were typical examples of chiral magnets that host stable magnetic skyrmions. Although skyrmion-host B20-type alloys have been intensively studied, the synthesis process have so far been limited to a high-pressure and high-temperature(HPHT) synthesis. Mechanical alloying is one of non-equilibrium processing techniques for the formation of several alloys and compounds that are difficult or impossible to be produced by a conventional melting process. In this study, we applied mechanical alloying to synthesize B20-type TMGe, and successfully obtained several B20-type alloys without a HPHT synthesis.
