The dark traces induced by high‐power laser radiation in LiNbO3:Mg and LiNbO3:Zn are found to be reduced by annealing the crystals in an O2 atmosphere. Most of the decrease of the second‐harmonic generation efficiency η for 1064–532 nm convers

We have measured the Seebeck coefficient and the resistance under light illumination of 365 nm in a ceramic sample of ZnO at 100, 150, and 200 K, and have analyzed the photo-Seebeck coefficient and the photoconductivity using a two-layer model. We ha

We report photoconductivity measurements in a binary system of naphthalene-based liquid crystals. Under ultraviolet (365 nm) illumination we observe an anomalous increase in the photocurrent for the mixtures. For a particular concentration, the photo

Substitution of Ni for Mn in La0.67Sr0.33MnO3 (LSMO) lowers the Curie temperature TC from 365 K for LSMO to 194 K for La0.67Sr0.33(Mn0.8Ni0.2)O3, which exhibits a cluster glass-like state. The oxide is insulating under both zero field and 60 kOe, but

Structural and magnetic properties of RFe11.3Nb0.7 compounds with rare-earth elements (R=Y, Sm, Gd, Tb, Dy, Ho, and Er) have been investigated. The Curie temperature increases for R=Sm–Gd, then decreases from R=Gd to Er. In the compound with R=Tb,
