Experimental Evidence for Two-Dimensional Magnetic Order in Proton Bombarded Graphite
arXiv:0706.2442 · doi:10.1103/PhysRevB.76.161403
Abstract
We have prepared magnetic graphite samples bombarded by protons at low temperatures and low fluences to attenuate the large thermal annealing produced during irradiation. An overall optimization of sample handling allowed us to find Curie temperatures K at the used fluences. The magnetization versus temperature shows unequivocally a linear dependence, which can be interpreted as due to excitations of spin waves in a two dimensional Heisenberg model with a weak uniaxial anisotropy.
