Anisotropy in the <i>g</i>-factors of conduction electrons in bcc transition metals (vanadium, niobium, and tantalum)

The Zeeman splitting for conduction electrons in transition d-metals (vanadium, niobium, and tantalum) is investigated theoretically by the RLMTO method. The results of calculation and averaging of g-factors are presented, together with the results of analysis of their stability to variations of the density of states, and also the results of calculation of the enhancement of the Zeeman splitting of levels due to electron-electron interaction. The orbit-averaged g-factors display anisotropy on the octahedral O2 hole sheet of the Fermi surface of the second band. The results of calculations are compared with experimental results and with the results obtained by other authors. Some general regularities in the behavior of the g-factors for all transition d-metals of the cubic structure are formulated.
