Magneto-optic effects in spin-injection devices

June 23, 2003
Author(s)
Steve Ruggiero, Anthony Williams, Carol Tanner, S. Potashnik, John M. Moreland, William Rippard
The magneto-optic properties of semi-transparent ferromagnetic films are presented in the context of ferromagnet/GaAs spin-injection devices. We have measured the polarization-dependent photoresponse and magneto-optic properties of Co/i}n-GaAs, Co/p-GaAs

T c Suppression in Superconducting Films for use in Transition Edge Sensors

June 1, 2003
Author(s)
Steven Deiker, Gene C. Hilton, Kent D. Irwin, William Rippard, Steve Ruggiero, Leila R. Vale, B. A. Young
Transition edge sensor (TES) microcalorimeters have proved their value as photon detectors in several wavelength regimes. The central elecement of a TES is a superconducting film with a transition temperature designed to be at a specific temperature
