✦ Synopsis

The picosecond photoinduced absorption features of a thin Elm of the a-coupled sexithiophene oligomer have been measured using the Kerr ellipsometry technique. Spectral and dynamic studies of the sharp transient absorption peak induced in the transparency region of the oligomer are presented. Its origin is attributed to a triplet-triplet absorption. The reasons for its narrow line shape are discussed.

Magnetic circular dichroism (MCD) in superconducting and insulating YBa2Cu3Ox thin films is studied. The MCD spectra in superconducting samples exhibit a linearly field dependent structure at 4-5 eV. The field and temperature dependences, the latter seeming to obey the Curie law, suggest that this s
