Metallic Microwave Conductivity in Shock-Loaded Rutile
Electron spin resonance (ESR) has been used to characterize the paramagnetic defects present in both single crystal and powder rutile (TiO2) subjected to explosive shock loading and preserved for post-shock study...

Transmission Electron Microscopy of Shock-Modified and Annealed Rutile
The annealing behavior of shock modified rutile (TiO2) powder was studied by transmission electron microscopy, x-ray line broadening, and electron spin resonance. Specimens were examined in the as-received and as...

Tetrahedral and Octahedral Site Occupancy and Optic Mode Vibrations Mode Vibrations of Hydrogen in Yttrium
The yttrium-hydrogen system exhibits both tetrahedral and octahedral site occupancy prior to reaching the dihydride concentration. Using the WNR pulsed neutron source at the Los Alamos National Laboratory, tem...

Proton NMR Studies of the Electronic Structure of ZrHx
The proton spin-lattice relaxation times and Knight shifts have been measured in f.c.c. (δ-phase) and f.c.t. (ε-phase) ZrHx for 1.5 ≤ x ≤ 2.0. Both parameters indicate that N(EF) is very dependent upon hydrogen c...

Octahedral Site Occupation in Lanthanum Dihydride
The distribution of hydrogen ions among the octahedral and tetrahedral sites in lanthanum hydride has been determined at liquid helium temperatures for hydrogen/metal ratios from 1.90 to 2.04. Electron spin re...
