Three-Dimensional Shankar Skyrmions in Frustrated Antiferromagnets
This work develops a unified continuum theory to study finite-size 3D Shankar skyrmions in frustrated antiferromagnets. By including competing energy scales like exchange, DMI, anisotropy, and frustration, the authors show how these interactions stabilize finite-size textures with integer winding. This establishes frustrated chiral antiferromagnets as viable hosts for complex 3D non-Abelian topological magnetic textures.
