Low field colossal anisotropic magnetoresistance in spatially confined electronically phase separated La{sub 0.3}Pr{sub 0.4}Ca{sub 0.3}MnO{sub 3} microbridges
Colossal in-plane anisotropic magnetoresistance (AMR) of >16 000% has been engineered in spatially confined La{sub 0.3}Pr{sub 0.4}Ca{sub 0.3}MnO{sub 3} films. Recalling that typical AMR values in films are only a few percent, these results mark an astonishing increase that might potentially lead to fabrication of manganite-based switching and sensor devices. The unique colossal behavior is discussed within the context of anisotropic domain growth.
