Spin-polarized two-dimensional electron gas at oxide interfaces.
The possibility of formation of a fully spin-polarized 2D electron gas at the SrMnO_3/(LaMnO_3)_1/SrMnO_3 heterostructure is predicted from density-functional calculations. The La(d) electrons become confined in the direction normal to the interface in the electrostatic potential well of the positively charged layer of La atoms, acting as electron donors. These electrons mediate a ferromagnetic...
متن کاملNonequilibrium Electron Cooling by NIS Tunnel Junctions
We discuss the theoretical framework to describe quasiparticle electric and heat currents in NIS tunnel junctions in the dirty limit. The approach is based on quasiclassical Keldysh-Usadel equations. We apply this theory to diffusive NIS′S tunnel junctions. Here N and S are respectively a normal and a superconducting reservoirs, I is an insulator layer and S′ is a nonequilibrium superconducting...
متن کاملMetal-Oxide Interfaces in Magnetic Tunnel Junctions
Metal-oxide interfaces play an important role in spintronics—a new area of microelectronics that exploits spin of electrons in addition to the traditional charge degree of freedom to enhance the performance of existing semiconductor devices. Magnetic tunnel junctions (MTJs) consisting of spin-polarized ferromagnetic electrodes sandwiching an insulating barrier are such promising candidates of s...
