Abstract
This thesis studies the anisotropic magneto-resistance (AMR) in electronically phase separated La0.7-xPrxCa0.3MnO3 (LPCMO) epitaxial thin films. Different Pr doping levels, epitaxial strain, magnetic fields, temperature and two dimensional confinement effects have been used to understand this fundamental spintronics property in such strongly correlated manganite systems. We investigated four major problems associated with the AMR in phase separated manganites, including: carrier localization, crossover phenomena, metastability and spatial confinement effects. The experimental results obtained for the AMR of phase separated LPCMO films provide new information about the nature and dynamics of the AMR in strongly correlated manganite systems, and may lead to new investigations of the resistive-switching phenomena in magnetic storage devices and spintronics
