Magnetization simulation.

Hysteresis loops for a spherical (red circles, diameter 20 nm) and a cubic particle (blue squares, side 20 nm) obtained from MC simulations of an atomistic spin model of maghemite at low temperature. In both, uniaxial anisotropy at the core and Néel surface anisotropy have been considered. Snapshots show the spin configurations in the remanent state. Spins have been colored according to their projection into the magnetic field direction (z axis) from red (+1) to blue (−1).
