Spin+Control: Multiscale control of exchange-enhanced spin dynamics (B15*)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 268565370

In Project B15 we address the control of spin dynamics in antiferromagnets, altermagnets and their heterostructures with ferromagnets. We will explore from experimental and theoretical standpoints two different classes of control schemes. First, local control schemes that allow tailoring the transport of magnons in a spatially resolved fashion. Second, global control schemes that allow manipulating the overall magnon eigenmodes in an energy-efficient way. For local control, we exploit the impact of interfaces, thermal landscapes, and nontrivial magnetic textures on magnon spectra. In the inverse process, we will use magnon dynamics as a tool for reconstructing and manipulating magnetic textures. For global control we will employ uniform piezoelectric modulation of magnetic anisotropy.
