Surface-sensitive second-harmonic generation, with the proper choice of symmetry, has demonstrated an extremely high sensitivity for detecting surface magnetization on Si(111)-7×7 induced by an external magnetic field of 10 T. Electron spins at the dangling bonds are suggested to be responsible for the observed magnetization of surfaces of nonmagnetic semiconductors. The temperature dependence ...
The anisotropic paramagnetism and specific heat in Nd(2)Ti(2)O(7) single crystals are investigated. The angular dependence of the magnetization and Weiss temperatures show the dominant role of the crystal field effect in the magnetization. By incorporating the results from the diluted samples, contributions to the Weiss temperature from exchange interactions and crystal field interactions are i...
The stabilization the ground state of COT2Ce was evaluated to be 0.3 eV using a Hubbard model and from its temperature independent paramagnetism.
