M. Rubinstein et al., Investigation of granular films composed of interdispersed La1/3Ca2/3MnO3 particles and metallic Au particles, J APPL PHYS, 83(11), 1998, pp. 7067-7069
We have carried out a study of composite, granular films made by depositing
LCMO (a colossal magnetoresistive perovskite) and pure, metallic Au onto M
gO and LaAlO3 substrates. Elevated temperature caused the Au to segregate i
nto small, micron-sized granules. The films were studied by atomic force mi
croscopy, magnetoresistivity, superconducting quantum interference device m
agnetization measurements, and magnetically modulated microwave absorption.
