Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with a…

Kinetics of electric field induced oxygen ion migration in epitaxial metallic oxide films
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report the observation of curent induced change of resistance of thin metallic oxide films. The resistance changes at a very low current (current density $J \geq 1…
