 | 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 | Overcoming the slowing down of flat-histogram Monte Carlo simulations: cluster updates and optimized broad-histogram ensembles | We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensional ferromagnetic Ising/Potts models. We first show that flat-histogram Monte Carlo methods with single-spin flip upda... | Energy space; Spin dynamics; Density of states; Cluster dynamics | 2005-10 |

 | Vardeny, Zeev Valentine | Spin dynamics of triplet photoexcitations in C60: evidence for a dynamic Jahn-Teller effect | We have used the absorption-detected magnetic-resonance (ADMR) technique to study the spin dynamics of triplet photoexcitations in C60 molecules dispersed in polystyrene glasses. We found that the ADMR spectra contain two triplet powder patterns A and B with substantial spin reorientation dynamics,... | Spin dynamics; Triplet photoexcitations; C60 | 1995-07 |
