It begins with an introduction to the general concept of spin and spin current, which is followed by a ...
In acertain range of voltages, the spin current can exhibit a power dependence onthe ac voltage bias with a negative exponent. The spin current expressed inunits of $\\hbar/2$ per second can become much larger than the charge current inunits of the electron charge per second. The spin ...
Cubic materials host high crystal symmetry and hence are not expected to support anisotropy in transport phenomena. In contrast to this common expectation, here we report an anomalous anisotropy of spin current can emerge in the (001) film of Mn3Pt, a no
This mechanism is confirmed by renormalization group analysis and describes movable Kondo singlets called “holons” induced by an effective coupling between the spin current of conduction electrons and the vector chirality of localized spins. Similar mechanisms may widely exist in all frustrated Kondo ...
We reveal how the spin transport depends on interface resistance, electrode resistance, spin polarization and spin diffusion length, and obtain the conditions for efficient spin injection, spin accumulation and spin current in the device. It is demonstrated that the spin Hall effect is caused by ...
The spin current, orbit angular momentum current and total angular momentum current in a tensor form have been universally defined according to the quantum electrodynamics. Their conservation quantities and the continuity equations have been discussed in different cases. Non-relativistic approximation forms...
The meaning of SPIN is to draw out and twist fiber into yarn or thread. How to use spin in a sentence.
Magnon drop dynamics via exchange flows of spin current Analysis of the magnetisation dynamics from a micromagnetic perspective can shed light onto the origins of howLgrows during magnon coalescence. Interactions between magnon drops can be quantified and visualised in terms of the long-range transport...
We show that the injection of a pure spin current (not accompanied by charge current) into a ring can induce a circulating charge current in the ring, provided that transport coefficients of the ring are spin dependent and inhomogeneous. As an example, we consider a hybrid ferromagnet–normal-...
A spin current-electric current conversion structure using a material containing 5d-transition metal has low efficiency of spin current-electric current conversion; therefore, a spi
