Fig. 5: Biskyrmion generation and sustainability at zero fields via appropriate field-cooling (FC) manipulation in Tb0.2Gd0.8Co2.
From: Spontaneous Small Biskyrmions in a Centrosymmetric Rare-Earth Kagome Ferrimagnet
a Schematic demonstration of the FC procedure and experimental conditions. b Zero-field biskyrmions observed at 243 K after FC under 31 mT from 301 to 255 K and their evolution while decreasing the temperature to c 196 K and d 173 K. e Mixed state with stripes and fewer biskyrmions at 243 K after FC from 301 K under a magnetic field of 99 mT.
