Experiments debunk 'pseudogap' role in superconductivity
New research may pave way to practical superconductors
A phenomenon of solid-state physics known as "pseudogaps,"
suspected by some scientists of playing a key role in the mystery of
high-temperature superconductors, has now been found to occur in
materials of a completely different nature. This discovery casts new
doubts on any direct link between pseudogaps and high-temperature
superconductivity.
Working at the Advanced Light Source (ALS) of the Lawrence Berkeley
National Laboratory, multi-institutional collaborators led by
researchers with Berkeley Lab and Stanford University have identified
pseudogaps in manganites, manganese oxide materials that, below a
certain critical temperature, become ferromagnetic and
