From: Spontaneous symmetry breaking in vortex systems with two repulsive lengthscales

Calculated vortex configurations in a 160 nm thick MgB2 film (magnetic field distribution at 500 nm above the surface is shown), for parameters used to fit the experimentally measured Hc2(T) and applied magnetic field (a) 1.25 G (size 52.47 × 60.59 μm2), (b) 1.7 G (size 51.95 × 60 μm2) and (c) 2.2 G (size of the image 51.06 × 58.96 μm2).
Normalised histograms of the vortex-vortex separations are inset.
