• lengths are measured in units of the lattice constant a. To identify the superconductivity type, we analyze vortex configurations obtained from self-consistent microscopic calculations. We focus on configurations containing three vortices, which is sufficient to capture both vortex clustering and

• the type-I and IT regimes. The phase diagram in Figure 3 closely resembles that obtained within the EGL formalism in the κ–T-plane, where the GL parameter κ is related to the coupling strength g. The sequence of regimes, type I→IT→type II, persists at all temperatures. Thus, microscopic calculations

• coupled micromagnetic equations. The results we obtain are consistent both with a macroscopic Curie–Weiss type fitting and the microscopic calculations of Serantes and co-workers [10], which point to the primary importance of the shape anisotropy of nanoparticles and the resulting magnetic properties of
