Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets.

ABSTRACT: 2D chiral magnets are known to host a variety of skyrmions, characterized by an integer topological charge ( Q∈Z$Q \in \mathbb {Z}$ ). However, these systems typically favor uniform lattices as thermodynamically stable phases composed of either skyrmions (Q = -1) or antiskyrmions (Q = 1). In isotropic chiral magnets, skyrmion-antiskyrmion coexistence is typically transient due to mutual annihilation, making the observation of a stable, long-range, ordered lattice a significant challenge. Here, this challenge is addressed by demonstrating a skyrmion-antiskyrmion lattice as a magnetic field-induced topological ground state in chiral magnets with competing anisotropic interactions, specifically Dzyaloshinskii-Moriya and frustrated exchange interactions. This unique lattice exhibits a net-zero
