Asymmetric domain nucleation and unusual magnetization reversal in ultrathin Co films with perpendicular anisotropy
(American Physical Society, 2007-03-16)
We report unexpected phenomena during magnetization reversal in ultrathin Co films and Co/Pt multilayers with perpendicular anisotropy. Using magneto-optical Kerr microscopy and magnetic force microscopy we have observed ...
Effects of carrier mobility and morphology in organic semiconductor spin valves
(American Institute of Physics, 2009-05-01)
We studied spin transport in four organic semiconductors (OSCs) with different electronic properties. Magnetoresistance (MR) effects were observed up to room temperature in junctions based on an electron-carrying OSC, ...
Magnetic properties of one-dimensional quasiperiodic Co/Pt multilayers
(American Institute of Physics, 2006-04-15)
We have fabricated Fibonacci [Co/Pt] multilayers with two constituent Co/Pt bilayers, as well as periodic multilayers of the same Co/Pt bilayers, all of which exhibit perpendicular magnetic anisotropy. Magnetic properties ...
Current and shot noise measurements in a carbon nanotube-based spin diode
(American Institute of Physics, 2009-04-01)
Low-temperature measurements of asymmetric carbon nanotube (CNT) quantum dots are reported. The CNTs are end-contacted with one ferromagnetic and one normal-metal electrode. The measurements show a spin-dependent rectification ...
