Microstructure, interdiffusion and magnetic properties of ZnO/MnOx multilayers grown by pulse laser deposition

ZnO/MnOx nano-thin multilayers are fabricated by pulsed laser deposition with a sectioned target or “cake” technique. Structure and magnetic properties are measured, finding a magnetic signal that scales better with the number of interfaces than with the film volume, and an interlayer interdiffusion that happens at remarkably low film growth temperatures.
