Spin Densities

This article reviews steady-state spin densities and spin currents in materials with strong spin-orbit interactions. These phenomena are intimately related to spin precession due to spin-orbit coupling, which has no equivalent in the steady state of charge distributions. The focus will initially be on effects originating from the band structure. In this case, spin densities arise in an electric field because a component of each spin is conserved during precession. Spin currents arise because a component of each spin is continually precessing. These two phenomena are due to independent contributions to the steady-state density matrix, and scattering between the conserved and precessing spin distributions has important consequences for spin dynamics and spin-related effects in general. In the latter part of the article, extrinsic effects such as skew scattering and side jump will be discussed, and it will be shown that these effects are also modified considerably by spin precession. Theoretical and experimental progress in all areas will be reviewed.

The static spin susceptibility in high-temperature superconductors can be accurately determined by Nuclear Magnetic Resonance (NMR) measurements which show that it has a systematic doping and temperature dependence in the normal state. The similarity in the temperature dependence of the 89Y, 63Cu and 17O Knight shifts for YBa2Cu3O7−δ as well as for YBa2Cu4O8 demonstrate that all of them probe the same spin susceptibility, Xs(T). This provides strong evidence in favor of the one-band model in which the Cu 3d and O 2p orbitals hybridize strongly and form a single quantum spin fluid in the Cu−O plane. Furthermore, recent NMR work has revealed a common behavior in the underdoped regime: similar magnitudes and temperature dependences of Xs(T) in different double layered superconducting cuprates are related to their similar Tc, suggesting a strong correlation between Tc, the hole density and the spin susceptibility. Possible explanations of the common behavior as well as the systematic doping and temperature dependence of the spin susceptibility in high-Tc cuprates are discussed.
