The ground-state of a paramagnet. Schematic representation of the intrinsic magnetic moments (black arrows) of the electrons (red spheres), separated by a distance r, for the Brillouin paramagnet. Upon lowering the temperature T1 > T2 > T = 0 K in the absence of external magnetic field, all magnetic moments are naturally aligned along the same direction and a magnetically ordered phase takes place, since an effective local magnetic field Bloc is intrinsically present due to the mutual interactions between adjacent magnetic moments3,4,11. Note the lack of perfect alignment of the magnetic moments in respect to Bloc, cf. discussion in the main text. Figure created with use of Adobe Illustrator (version CC 2017)62.
