Query: The electronic structure of La$_{1-x}$Sr$_{x}$MnO$_{3}$ thin films and
  its $T_c$ dependence as studied by angle-resolved photoemission   We present angle-resolved photoemission spectroscopy results for thin films
of the three-dimensional manganese perovskite La$_{1-x}$Sr$_{x}$MnO$_{3}$. We
show that the transition temperature ($T_c$) from the paramagnetic insulating
to ferromagnetic metallic state is closely related to details of the electronic
structure, particularly to the spectral weight at the ${\bf k}$-point, where
the sharpest step at the Fermi level was observed. We found that this ${\bf
k}$-point is the same for all the samples, despite their different $T_c$. The
change of $T_c$ is discussed in terms of kinetic energy optimization. Our ARPES
results suggest that the change of the electronic structure for the samples
having different transition temperatures is different from the rigid band
shift.
