abstract

The interplay between geometry and topology is of fundamental importance throughout many disciplines. In this respect, the investigation of physical effects governing the responses of curved magnetic nanoobjects to electric and magnetic fields is of strong fundamental interest but is also technologically appealing. Owing to intense theoretical and experimental efforts, the topic of magnetism in curved geometries has evolved in an independent research field of modern magnetism with many exciting theoretical predictions and strong application potential.

This talk focuses on the peculiarities emerging from geometrically curved magnetic objects, including two-dimensional bent wires, three-dimensional helices, three-dimensional curved shells, e.g. spherical or tubular and Möbius bands. During the talk, we will discuss two groups of curvature-induced effects in nanomagnets: (i) magnetochiral effects unite the phenomena of curvature-induced chiral symmetry breaking and (ii) topologically induced magnetization patterning which appears in curvilinear magnets, where the orientation of the effective anisotropy axis is determined by the geometry.
