The structure and dielectric properties of SrTiO3 thin films with either 5% Ca or Zr substitutions have been investigated. Thin films of these materials were deposited onto (100) LaAlO3 substrates by pulsed laser deposition (PLD) at temperatures of 7

Anomalous non-Gaussian effects appear in the resistance fluctuations of a macroscopic sample of the colossal magnetoresistive material La2/3Ca1/3MnO3. Individual resistance switches are frequently resolved. The results indicate the presence of highly

We report on the effect of the deposition temperature of SrTiO3 on the dielectric properties of SrTiO3/YBa2Cu3O7-δ/LaAlO3 thin film multilayer structures. In these structures, the YBa2Cu3O7-δ (YBCO) films were deposited at 800°C by laser ablation,
