Fig. 5: Field-free skyrmions under different tilt angles.

Underfocused LTEM images of field-free skyrmions taken at a defocus value of ~1 mm with tilting angle of 19° (a), 7° (b), 0° (c) and −20° (d) with respect to [001] direction. Skyrmion lattice was obtained after a field cooling with the magnetic field applied at 0°. A single skyrmions at oblique angles and corresponding experimentally measured magnetic contrast profile are shown in the bottom row.
