Spin Detection and Injection Using Ferromagnetic Metal and Semiconductor Hybrid Structure
We investigated spin-dependent transport properties from a viewpoint of spin detection and injection using a ferromagnetic metal / insulator (Al2O3)/ semiconductor tunnel junction with homogeneous and flat interfaces. For spin detection from the semiconductor, spin-polarized electrons were excited in the GaAs layer by circularly polarized light and injected into the permalloy layer. The energy ...
متن کاملFerromagnetic 0–π Josephson junctions
We present a study on low-Tc superconductorinsulator-ferromagnet-superconductor (SIFS) Josephson junctions. SIFS junctions have gained considerable interest in recent years because they show a number of interesting properties for future classical and quantum computing devices. We optimized the fabrication process of these junctions to achieve a homogeneous current transport, ending up with high...

متن کاملLarge magnetoresistance in a ferromagnetic GaMnAs/GaAs Zener diode
–We investigate spin-dependent interband tunnelling in a ferromagnetic (Ga,Mn)As/ GaAs Zener diode. The ferromagnetic pn-junction is fabricated with a Mn-doped p-type GaAs layer on top of a nonmagnetic n-type GaAs substrate. When both sides of the junction are heavily doped, a large magnetic-field–dependent tunnelling effect can be seen at low temperatures in the measured current-voltage (I-V )...
متن کاملHow to Measure Degree of Spin Polarization
Spintronics is an emerging field of research combining two traditional branches of physics: magnetism and electronics. It is based on the ability of ferromagnetic materials to conduct spin-polarized currents. The effectiveness of spintronics depends on the extent to which a current is spin-polarized [1], which in turn depends on the spin polarization of the ferromagnetic materials. All device d...
