Dispersion Line

Variations of microwave transmission coefficient through Fe films and Fe/Cr superlattices have been studied caused by ferromagnetic resonance at frequencies from 26 to 38 GHz. The shape of resonance line is described in frames of the model where its asymmetry is obtained by adding of lorenzian dispersion line to the absorption line. It has been shown that the shape of resonance line for superlattices with continuous Fe and Cr layers and also for Fe films is well described in this model. For the superlattices with thin Fe or Cr layers only qualitative agreement is observed. In magnetic fields less than the field of ferromagnetic resonance, essential distinction is observed of experimental magnetic field dependence of transmission coefficient comparing to the model, for superlattices which have giant magnetoresistive effect.

Abstract We show that a strong `spin'-orbit coupled one-dimensional (1D) hole gas is achievable via applying a strong magnetic field to the original two-fold degenerate (spin degeneracy) hole gas confined in a cylindrical Ge nanowire. Both strong longitudinal and strong transverse magnetic fields are feasible to achieve this goal. Based on quasi-degenerate perturbation calculations, we show the induced low-energy subband dispersion of the hole gas can be written as $E=\hbar^{2}k^{2}_{z}/(2m^{*}_{h})+\alpha\sigma^{z}k_{z}+g^{*}_{h}\mu_{B}B\sigma^{x}/2$, a form exactly the same as that of the electron gas in the conduction band. Here the Pauli matrices $\sigma^{z,x}$ represent a pseudo spin (or `spin' ), because the real spin degree of freedom has been split off from the subband dispersions by the strong magnetic field. Also, for a moderate nanowire radius $R=10$ nm, the induced effective hole mass $m^{*}_{h}$ ($0.065\sim0.08~m_{e}$) and the `spin'-orbit coupling $\alpha$ ($0.35\sim0.8$ eV~\AA) have a small magnetic field dependence in the studied magnetic field interval $1<B<15$ T, while the effective $g$-factor $g^{*}_{h}$ of the hole `spin' only has a small magnetic field dependence in the large field region.
