摘要：
A magnetic bimeron is a version of skyrmion, which is predicted for the in-plane magnetized thin films with interfacial Dzyaloshinskii-Moriya interaction. Here we theoretically investigate the possibility to create individual bimeron using stray field of magnetic force microscope (MFM) tip. We demonstrate that a local magnetization reversal of the film by localized MFM field in combination with an additional uniform perpendicular magnetic field enables the stable bimeron formation. The possibilities for detection of the bimeron by the methods of magnetic force microscopy, Lorentz transmission electron microscopy and magnetic resonance force spectroscopy are discussed.
