Spin Hall Current and Spin-transfer Torque in Ferromagnetic Metal
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 in the first order in SOI, where
is the spin Hall current driven by an
external electric field. This is a reaction to inverse spin Hall effect driven
by spin motive force in a ferromagnet.Comment: 4 pages, Proceedings of the International Conference on Magnetism,

The boundary of the moduli space of stable cubic fivefolds
By GIT theory due to Mumford, the moduli space of stable cubic fivefolds is
compactified by adding non stable semi-stable (i.e. strictly semi-stable)
locus. In this paper, we prove that this locus consists of 19 components.
Moreover, we give a description of equation and singularity of cubic fivefold
corresponding to the generic point in each component.Comment: 14 page
