Abstract
- Magnetic skyrmions are nanoscale topological textures that have been recently observed in different families of quantum magnets. These objects are called CP <superscript>1</superscript> skyrmions because they are built from dipoles-the target manifold is the 1D complex projective space, CP <superscript>1</superscript> ≅ S <superscript>2</superscript> . Here we report the emergence of magnetic CP <superscript>2</superscript> skyrmions in a realistic spin-1 model, which includes both dipole and quadrupole moments. Unlike CP <superscript>1</superscript> skyrmions, CP <superscript>2</superscript> skyrmions can also arise as metastable textures of quantum paramagnets, opening a new road to discover emergent topological solitons in non-magnetic materials. The quantum phase diagram of the spin-1 model also includes magnetic field-induced CP <superscript>2</superscript> skyrmion crystals that can be detected with regular momentum- (diffraction) and real-space (Lorentz transmission electron microscopy) experimental techniques.<br /> (© 2023.
