The quasiclassical Green function formalism is used to describe charge and spin dynamics in the presence of spin-orbit coupling. We review the results obtained for the spin Hall effect on restricted geometries. The role of boundaries is discussed in the framework of spin diffusion equations.

this cross sectional study was carried out between 1993 to 1998 at razi skin hospital, the affiliated dermatology department of tehran university of medical sciences. eight hundred patients receiving etretinate for various skin diseases took part in this study. among them, 457 patients with first admission to dermatologic clinic who had at least four regular sequential visits and responding to ...

background and objectives: calamus rotang is used in traditional medicine. regarding the previous phytochemical screening of methanol extract of calamus rotang l. fruits (mcr), this study was performed to find out the antidiarrheal and hypoglycemic effects of the experimented extract in rodents. methods: castor oil induced diarrheal test was followed for screening anti-diarrheal effect of mcr. ...

We theoretically examine the spin-transfer torque in the presence of spin-orbit interaction (SOI) at impurities in a ferromagnetic metal on the basis of linear response theory. We obtained, in addition to the usual spin-transfer torque, a new contributioin ∼ jSH ·∇n in the first order in SOI, where jSH is the spin Hall current driven by an external electric field. This is a reaction to inverse ...
