Elastic and Inelastic Spin Transport in SrTiO ₃ ‐based Magnetic Heterostructure

Negative spin polarization and large tunneling magnetoresistance in epitaxial Co/SrTiO(3)/Co magnetic tunnel junctions.

We perform an ab initio study of spin-polarized tunneling in epitaxial Co/SrTiO(3)/Co magnetic tunnel junctions with bcc Co(001) electrodes. We predict a large tunneling magnetoresistance in these junctions, originating from a mismatch in the majority- and minority-spin bands both in bulk bcc Co and at the Co/SrTiO(3)/Co interface. The intricate complex band structure of SrTiO(3) enables effici...

high spin states in deep-inelastic and compound-nucleus reactions

compound-nucleus reactions provide the standard mechanism to populate states with high angularmomentum in neutron deficient nuclei. neutron-rich nuclei with mass aand induced fission. projectile fragmentation has proven to be an efficient method of populating nuclei farfrom the valley of stability. however, in the case of heavy nuclei this method is still limited to species withisomeric states....

Spin Dependent Transport in Magnetic Nanostructures

Recent progress in physics on spin dependent transport in magnetic nanostructures is reviewed. Special attention is paid on the spin accumulation and spin current caused by spin injection into non-magnetic metals and semiconductors and superconductors. A variety of phenomena induced in nano-superconductor/ferromagnet devices are proposed, examining the spin-charge separation in superconductors.

Reference Transport through Graphene on SrTiO

We report transport measurements through graphene on SrTiO3 substrates as a function of magnetic field B, carrier density n, and temperature T. The large dielectric constant of SrTiO3 very effectively screens long-range electron-electron interactions and potential fluctuations, making Dirac electrons in graphene virtually noninteracting. The absence of interactions results in an unexpected beha...
