Effects of crystal field and momentum-based frustrated exchange interactions on multiorbital square skyrmion lattice

Satoru Hayami, Yan S. Zha

Interorbital coupling, frustrated exchanges at higher harmonics, and crystal-field anisotropy together stabilize square skyrmion lattices in multiorbital Ce magnets.

Claims

C1strongest claim

The cooperative interplay among interorbital coupling, frustrated exchange interactions at higher-harmonic wave vectors, and crystal-field-induced anisotropy is crucial for the stabilization of the S-SkL. Furthermore, the competition between the easy-plane intraorbital anisotropy and the easy-axis interorbital anisotropy leads to a significant enhancement of the S-SkL stability region.

C2weakest assumption

That self-consistent mean-field theory on a multiorbital Hubbard-like model with chosen exchange parameters and crystal-field splittings faithfully captures the ground-state energetics of real Ce-based tetragonal magnets without significant fluctuation corrections or higher-order interactions.

C3one line summary

Cooperative interplay of interorbital coupling, higher-harmonic frustrated exchanges, and competing crystal-field anisotropies enlarges the stability region of square skyrmion lattices and produces several multi-Q states including a slightly symmetry-broken S-SkL variant.
