The second funding period of the project focuses on the theoretical understanding of (i) magnetization-induced deformations of 2D magnetic nanoobjects with various types of magnetic ordering and (ii) curvature-induced effects in altermagnets, including field- and current-driven dynamics of altermagnetic domain walls. The two central aims are: (i) to formulate a general phenomenological theory of magnetization-induced deformations in magnetoelastic systems, enabling the prediction of numerous new effects, particularly deformations induced by topological solitons; and (ii) to describe field-induced motion of altermagnetic domain wall in curved geometry, a phenomenon not observed in conventional antiferromagnets. My work will be based on both analytical approaches and numerical spin-lattice simulations, with a particular emphasis on integrating these methods.
