Abstract
We have studied the variation of the density of states (DOS) near the Fermi
energy E-f of Pr0.5Sr0.5MnO3 thin film as a function of temperature using
scanning tunneling microscope (STM). The tunneling spectroscopy exhibits sp
ectral changes in the density of state across Neel temperature (T-N similar
to 160 K) and Curie temperature (T-C similar to 240 K). The DOS near E-f s
hows strong temperature dependence. (C) 2000 Elsevier Science B.V. All righ
