Description:

(abstract)

The spin reorientation in rare-earth intermetallics involve distinctive magnetic morphologies commencing with spontaneous skyrmion textures without an external magnetic field. Here, we present the sputtering growth of CaCu5-type NdCo5-xCux thin films on MgO (110) substrate. Our films exhibit the two successive spin reorientation transitions between the ab-plane and the c-axis, close to the room temperature, apart from the non-uniaxial behavior below 150 K. The corresponding modulations of magnetocrystalline anisotropy at reorientation temperatures leads to the large topological Hall effect, which can be maintained up to 250 K. These results of robust topological signals will provide platforms for realizing room-temperature topological magnetic textures.
