“…When self-consistency was achieved the spin and orbital moments were computed as described by Brooks and Kelly [1]. As has been shown earlier, incorporation of an external magnetic field in this way reproduces the ahisotropy of the Zeeman splitting over Fermi-surface sheets as well as the total susceptibilities [11,12]. These successful applications of the present theory suggest that this is a suitable tool for studies of the electronic and magnetic structure of metals in external magnetic fields.…”

An example of a breakdown of Hund's third rule for a system with less than a half filled electronic shell is presented. By means of spin polarized electronic structure calculations including the relativistic effects and a Zeeman term, we demonstrate that in the field induced magnetic state of uranium the spin and orbital moments are coupled parallel rather than antiparallel as stipulated by Hund's third rule. This provides an explanation for the measured field induced magnetic form factor of uranium metal.

“…The method we have used was recently discussed in detail [11,12] and therefore we will only give a brief description here. The calculations were based on the local spin density approximation (LSDA) and the basis functions employed were the linear muffin-tin orbitals in the atomic sphere approximation (LMTO-ASA) [13,14].…”

“…Also, unlike Pd, relativistic effects are important in its electronic structure. 16 Here we report 8 Li β-detected nuclear magnetic resonance (β-NMR) and relaxation rate measurements in Pt. The β-NMR technique gives us the unique opportunity to explore several aspects of the implantation of a spin polarized radioactive 8 Li + ion in Pt.…”

We report β-detected nuclear magnetic resonance (β-NMR) measurements of 8 Li + implanted into high purity Pt. The frequency of the 8 Li β-NMR resonance and the spin-lattice relaxation rates 1/T 1 were measured at temperatures ranging from 3 to 300 K. Remarkably, both the spin-lattice relaxation rate and the Knight shift K depend linearly on temperature T although the bulk susceptibility does not. K is found to scale with the Curie-Weiss dependence of the Pt susceptibility extrapolated to low temperatures. This is attributed to a defect response of the enhanced paramagnetism of Pt, i.e., the presence of the interstitial Li + locally relieves the tendency for the Curie-Weiss susceptibility to saturate at low T . We propose that the low temperature saturation in χ of Pt may be related to an interband coupling between the s and d bands that is disrupted locally by the presence of the Li + .

“…On the other hand, in many papers, see, e.g., Refs. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], the so-called local g factors g( ) k introduced by De Graaf and Overhauser [27] for points k on the Fermi surface were calculated, and the g factor of the orbit was obtained by integration of g( ) k over the orbit. In this symplified approach the dynamics of the electron spin is neglected completely.…”

At present, explicit expressions for the electron g factor in crystals are known only for the following two cases: either the Fermi energy e F of the electrons lies at the edge of the electron energy band, e ( ) k ex , or the electron energy spectrum of a crystal can be approximated by the two-band model. Here we obtain explicit formulas for the g factor in situations when the Fermi level e F is close to but does not coincide with the band edge and when the two-band model of the spectrum includes small corrections from other electron energy bands. In particular, we derive the expressions that describe the dependences of the g factor on e e F -( ) k ex and on the direction of the magnetic field for doped semiconductors. The results are applied to III-V semiconductors and to bismuth.
