Magnetic oxide thin films

Thin films of manganese or cobalt oxides exhibiting colossal magnetoresistance have been prepared using the same deposition methods as those used in the growth of superconducting cuprates. The thin film morphology, as well as the physical properties of the manganese oxide thin films, is shown to be strongly dependent on thin film growth. Devices, including these manganese oxides, have been grown to achieve a better sensitivity of their colossal magnetoresistance behavior to a magnetic field.
