Query: Quasiparticle Mass Enhancement and Temperature Dependence of the
  Electronic Structure of Ferromagnetic SrRuO3 Thin Films   We report high-resolution angle-resolved photoemission studies of epitaxial
thin films of the correlated 4d transition metal oxide ferromagnet SrRuO3. The
Fermi surface in the ferromagnetic state consists of well-defined Landau
quasiparticles, exhibiting strong coupling to low-energy bosonic modes which
contributes to the large effective masses observed by transport and
thermodynamic measurements. Upon warming the material through its Curie
temperature, we observe a substantial decrease in quasiparticle coherence, but
negligible changes in the ferromagnetic exchange splitting, suggesting that
local moments play an important role in the ferromagnetism in SrRuO3.
