Abstract We measured the spin rectification effect and the inverse spin Hall effect in Nb-doped SrTiO 3 by pumping the spins from the ferromagnetic thin films into SrTiO 3 . The spin injection is increased when the doping level is increased. However, the spin to charge conversion efficiency which is measured by the spin Hall angle decreases when Nb concentration is more than ∼ 0.02 wt%. We argued that it is because that the electrons contributed to the inverse spin Hall effect are from the d… Expand

Large linear magnetoresistance in heavily-doped Nb:SrTiO3 epitaxial thin films
TLDR
These phenomena are associated with the interplay between the large classical MR due to high carrier mobility and the electronic localization effect due to strong spin-orbit coupling, implying that heavily Nb-doped Sr(Nb0.2Ti0.8)O3 is promising for the application in spintronic devices. Expand
