Abstract

Magnetic anisotropy in ultrathin films of doped rare earth maganites with on their high degree of spinpolarization attracts increasing interest, both, from fundamental physics aspects as well as aspects due to its potential application in novel spintronics devices.
We approach the problem by two different experimental routes. One is based on the application of SrTiO3 single-crystal (100) oriented substrates with a vicinal cut along the [010] direction to tailor the in-plane magnetic anisotropy along the [100] direction, the other makes use of the compressive epitaxial strain between a CaMnO3 layer and the ferromagnetic La-Sr-Mn-O film to generate a perpendicular magnetic anisotropy.
The films a produced by the pulsed laser deposition technique and characterized by structural [ x-ray, TEM ] as well as transport and magnetic measurements.
