We consider the single-electron transistor with ferromagnetic outer electrodes and nonmagnetic island. Tunneling current causes nonequilibrium electron-spin distribution in the island. The dependencies of the magnetoresistance ratio on the bias and gate voltages show the dips which are directly rela

Spin dependent transport in a high mobility two dimensional electron gas (2DEG) with an asymmetric conΓΏning potential is observed by using a ferromagnetic metal as a spin sensitive voltage probe. A high impedance junction is formed between the ferromagnet and the 2DEG on a planarized sample. The con
We report detailed transport studies on ferromagnet-superconductor heterostructures. Epitaxial heterostructures of half-metal colossal magnetoresistive La 2/3 Ca 1/3 MnO 3 (HM-CMR) and high-T c superconducting YBa 2 Cu 3 O 7Γd (HTSC) are grown on SrTiO 3 (1 0 0) single crystal substrates using pulse
