Longitudinal field (LF) muon-spin-relaxation measurements have been performed for polythiophene based polymers of regio-random poly(3-hexylthiophene-2,5-diyl) to elucidate the intra-and interchain hopping mechanisms. The LF dependent muon-spin depolarization rate indicates the occurrence of pronounc
A series of oxygen-rich phases with formal stoichiometry La 2 Co x Cu 1؊x O 4؉ has been prepared. The excess of oxygen defects (0.064 40.20) that can be accommodated in the structure is higher than that found in the parent superconducting La 2 CuO 4؉ phase. The ac and dc susceptibility measurements

## Abstract Carbon‐13 spin–lattice relaxation times were measured for some penta‐ and tricarbonylchromium complexes of organic ligands. The chemical shift anisotropy of the carbonyl carbons was estimated to be __ca.__ 500 ppm. The contributions of dipole–dipole and chemical shift anisotropy mechani
