Figure 2: Magnetic configurations of the biskyrmions.
From: Biskyrmion states and their current-driven motion in a layered manganite
(a) The spin texture of biskyrmion lattice. (b) The in-plane magnetic component (yellow arrows) distribution in the biskyrmion lattice. (c,d) The over-focused (c) and under-focused (d) Lorentz TEM images for a biskyrmion. (e) The magnified view of spin texture for a biskyrmion. In a and e, colours and white arrows represent the magnitude and orientation of in-plane magnetizations, while the dark colour depicts the upward (downward) magnetizations in the core (periphery) of the biskyrmions. In (b–e), ‘plus’ (+) and ‘minus’ (−) indicate the magnetic helicity, that is, the clockwise and counter-clockwise rotating directions of in-plane magnetizations around the core, respectively. They are not the directions of magnetization along the z axis. Scale bar in c corresponds to 100 nm.
