Spin Transfer Torques in MnSi at Ultralow Current Densities
Spin Control Controlling and manipulating the spin of an electron is a central requirement for applications in spintronics and an efficient and simple superconducting-based single-electron transistor that can produce spin current with controlled flow is designed and fabricated.
New perspectives for Rashba spin-orbit coupling.
This Review discusses relevant recent and ongoing realizations of Rashba physics in condensed matter, ranging from layered graphene-like materials to cold atoms.
Long-distance transport of magnon spin information in a magnetic insulator at room temperature
Although electron motion is prohibited in magnetic insulators, the electron spin can be transported by magnons. Such magnons, generated and detected using all-electrical methods, are now shown to…
Magnon spin transport driven by the magnon chemical potential in a magnetic insulator
We develop a linear-response transport theory of diffusive spin and heat transport by magnons in magnetic insulators with metallic contacts. The magnons are described by a position-dependent…
Influence of yttrium iron garnet thickness and heater opacity on the nonlocal transport of electrically and thermally excited magnons
We studied the nonlocal transport behavior of both electrically and thermally excited magnons in yttrium iron garnet (YIG) as a function of its thickness. For electrically injected magnons, the…
Asymmetric magnetic bubble expansion under in-plane field in Pt/Co/Pt: Effect of interface engineering
We analyze the impact of growth conditions on the asymmetric magnetic bubble expansion under an in-plane field in ultrathin Pt/Co/Pt films. Specifically, using sputter deposition, we vary the Ar…
Theory of spin torques and giant magnetoresistance in antiferromagnetic metals
Spintronics in ferromagnetic metals is built on a complementary set of phenomena in which magnetic configurations influence transport coefficients and transport currents alter magnetic…
Magnon-drag thermopower and Nernst coefficient in Fe, Co, and Ni
Magnon drag is shown to dominate the thermopower of elemental Fe from 2 to 80 K and of elemental Co from 150 to 600 K; it is also shown to contribute to the thermopower of elemental Ni from 50 to 500…
Pinning of vortices in a Bose-Einstein condensate by an optical lattice.
We consider the ground state of vortices in a Bose-Einstein condensate. We show that turning on a weak optical periodic potential leads to a transition from the triangular Abrikosov vortex lattice to…
