We report experimental results of the characterization of an N+GaAs photodetector irradiated by fast neutrons with flux up to doses of 4×1017 n/cm2 using a constructed electro-optic sampling system and illumination with 80-fs-wide laser pulses. The

International Conference on Solid State Crystals '98: Single Crystal Growth, Characterization, and Applications.
The investigations of the Raman scattering spectra of the KDy(WO4)2 single crystals have shown that the phase transitions found at 6.38 K exhibit the peculiarities characteristic of SPT Jahn-Teller type. The paper presents also the results of IR abso

The magnetic properties, structure, microstructure, and chemical composition of new phases found in melt‐spun Nd‐Fe alloys are reported. High coercivities were obtained in ribbons after a heat treatment for 10–15 min at temperatures in the rang

SmCo5−xNix ribbons show a giant magnetic hysteresis with the maximum coercivity obtained in the x=1 sample. For the same composition, x‐ray diffraction studies show the existence of some texture with the c axis perpendicular to the ribbon. For x=

The underdoped NdBa 2 Cu 3 O 6.67 ceramic, with superconductivity induced in a slow oxygen-ordering process under pressure, was investigated. The room-temperature time evolution of lattice parameters after 1.3 GPa pressure release was determined by X

Large coercive fields (above 10 kOe) have been produced in thin sputtered films of Nd(FeCo)B. The films were either deposited at room temperature and heat treated or deposited onto high-temperature substrates (to about 730 °C). Transmission electron

Transmission electron microscopy, electron diffraction, and Lorentz microscopy are used to study the changes in morphology, structure, and magnetic domain structure during crystallization of amorphous (14 to 30%) MnGa thin films. The amorphous films
