Web9 de abr. de 2015 · We demonstrate by high resolution low temperature electron energy loss spectroscopy (EELS) measurements that the long range ferromagnetic (FM) order in the vanadium- (V-)doped topological insulator Sb 2 Te 3 has the nature of van Vleck–type ferromagnetism. The positions and the relative amplitudes of two core-level peaks (L 3 … WebWe now extend the concept of exchange to include interactions through a three- dimensional (3D) crystalline lattice. The interactions themselves are short-ranged, and probably are important only for the first through fourth nearest neighbors, but the effects are observed over large distances in a sample. Transitions to long-range order from the ...
