摘要：
We investigate the spin transport through strongly anisotropic noncollinear magnetic molecules and find that noncollinear magnetic quantum states act as spin-switching devices for the current. Moreover, spin currents are shown to offer a viable route to selectively prepare the molecular device in one of two degenerate noncollinear magnetic states. Spin currents can be also used to create a nonzero density of toroidal magnetization in a recently characterized Dy-3 noncollinear magnet.
