Fig. 2: Formation of square antiskyrmions.
From: Elliptical Bloch skyrmion chiral twins in an antiskyrmion system

The figure shows the evolution of the LTEM contrast with decreasing field applying the modified experimental protocol (applying reversible tilting along [1 1 0] at high fields until a lattice of objects has formed) at the highest investigated temperature of 350 K. We observe the transition from the field-polarized state, to a few isolated objects in a, to a lattice of square antiskyrmionic features in b, c, to the helical phase in d–f. The scale bar corresponds to 500 nm.
