Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Comment on "Frequency response and origin of the spin-½ photoluminescence-detected magnetic resonance in a ∏-conjugated polymer | In a recent paper, Segal et al. [Phys. Rev. B 71, 245201 (2005)] advanced a new explanation for the dynamics of spin-1/2 photoluminescence-detected magnetic resonance (PLDMR) in films of a rr-conjugated polymer, namely, a soluble derivative of poly(phenylene-vinylene) (MEH-PPV), using a model [dubbe... | Photoluminescence-detected magnetic resonance; PLDMR; pi-conjugated polymers; Poly(phenylene-vinylene); MEH-PPV | 2007-06 |

Vardeny, Zeev Valentine | Spin dynamics in organic spin valves based on La⅔Sr⅓MnO3 electrodes | We fabricated spin-valve devices made of organic semiconductor thin films sandwiched between ferromagnetic half-metal La2/3Sr1/3MnO3 (LSMO) and cobalt electrodes, using three different organic molecules. Subsequently, we studied the spin injection and transport properties by measuring the device mag... | Spin dynamics; Organic spin-valves; Spin response; OSEC | 2007-06 |

Wu, Yong-Shi | Universal distribution of spectral-flow gaps in the Rashba model with disorder | We report a study of disordered electron systems with spin-orbit coupling on a cylinder using methods of random matrix ensembles. With a threading flux turned on, the single-particle levels will generally avoid, rather than cross, each other. Our numerical study of the level-avoiding gaps in the d... | Rashba model; Spectral flow | 2007-06 |
