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 |

Scarpulla, Michael | Determination of the infrared complex magnetoconductivity tensor in itinerant ferromagnets from Faraday and Kerr measurements | We present measurement and analysis techniques that allow the complete complex magnetoconductivity tensor to be determined from midinfrared (11-1.6 μm; 100-800 meV) measurements of the complex Faraday (θF) and Kerr (θK) angles. Since this approach involves measurement of the geometry (orientati... | Magnetoconductivity tensor; Ferromagnets | 2007-06 |

Furse, Cynthia M. | Improving communication skills through project-based learning | In 2006, a program geared towards integrating technical communication and teamwork within engineering at the University of Utah was initiated. The program's aim was to improve communication education using technical course assignments, thereby avoiding the addition of a technical elective to an alre... | 2007-06 | |

Scarpulla, Michael | Magnetocrystalline anisotropy and magnetization reversal in Ga1-xMnxP synthesized by ion implantation and pulsed-laser melting | We report the observation of ferromagnetic resonance (FMR) and the determination of the magnetocrystalline anisotropy in (100)-oriented single-crystalline thin film samples of Ga1−xMnxP with x=0.042. The contributions to the magnetic anisotropy were determined by measuring the angular and the te... | Magnetocrystalline anisotropy; GaMnAs; Gallium arsenide | 2007-06 |

Furse, Cynthia M. | Recovering handset MIMO capacity with polarization-agile antennas | Multiple Input Multiple Output (MIMO) communication systems rely on significant variation between multiple signal paths to create independent channels for communication. Transceiver signal strength to or from a portable handset is subject to large variations due to the "essentially random orientatio... | 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 |
