Electron spin resonance (ESR) experiments at 4.15 K of Er 3 ÷ in YBiPt show that Er 3 ÷ is in a site of cubic local symmetry, with a Ft83) ground state and an overall crystal field splitting of ~ 85(10) K. We inferred from the spectra the existence of lattice distortions at the rare-earth (RE) site. These results may help in understanding the heavy-fermion system YbBiPt, which has the same structure as YBiPt.

“…The GeO 2 exhibits a low interfacial density of states to the bulk Ge, allowing for formation of high quality gates for control of spin and charge transport. Moreover, spin injection and spin relaxation in Ge have been extensively studied using electron spin resonance [20][21][22][23][24][25] and optical techniques [26][27][28][29]. However, in spite of all the recent progress in the Ge field and in contrast to Si, spin transport in Ge using nonlocal four-terminal techniques has only been observed at low temperatures to date [30][31][32].…”

Germanium (Ge) is another group-IV semiconductor material, which recently started attracting tremendous attention in spintronics following success of silicon (Si). The crystal inversion symmetry of Si and Ge precludes the spin relaxation of conduction electrons by the Dyakonov-Perel mechanism, resulting in a long spin relaxation time. Since the proposal of the spin FET in 1990 by Datta and Das, semiconductor materials have been studied for their spin-orbit (S-O) interactions, particularly those that can be modified by an applied electric field, such as the Rashba S-O interaction, in order to create devices that utilise spin modulation and control to perform logic operations. Since then new proposals have appeared. Nowadays they include spin transistors with several different operating principles, spin-based diodes, spin-based field programmable gate arrays, dynamic spin-logic circuits, spin-only logic, spin communication and others. In this review, the focus will be made on presenting recent progress in Ge spintronics including the key advances made. The absence of Dresselhaus S-O coupling in Ge enables a longer spin diffusion length when compared to III-V semiconductor materials. Evidence of a strong Rashba S-O interaction in strained Ge quantum wells has begun to emerge. Also, the first experimental demonstration of room-temperature spin transport in Ge has recently been reported.

Electron spin dynamics of the superconductorCaC6probed by ESR

et al. 2008

Conduction Electron Spin Resonance (CESR) was measured on a thick slab of CaC6 in the normal and superconducting state. Non-linear microwave absorption measurements in the superconducting state describe CaC6 as an anisotropic BCS superconductor. CESR data in the normal state characterize CaC6 as a three-dimensional (3D) metal. The analysis suggests that the scattering of conduction electrons is dominated by impurities and supports the description of superconductivity in the dirty limit. A surprising increase of the CESR intensity below Tc can not be explained by the theoretically predicted change in spin susceptibility. It is interpreted as a vortex enhanced increase of the effective skin depth. The study of the spin dynamics in the superconducting state and the discovery of the vortex enhanced increase of the skin depth poses a challenge to theory to provide a comprehensive description of the observed phenomena.
