Metastable vortex structures in a Bi2Sr2CaCu2Ox plate
Martynovich A. Yu.
Two stable vortex structures can coexist in Bi2Sr2CaCu20;c plates, which have an exceedingly pronounced crystalline anisotropy. One configuration is a slightly hexagonal lattice; the other is a configuration of vortex chains. These metastable structures coexist at small values of the induction (B<20 G) in a sufficiently thick plate (ά>20λα).
