Observation of the developed Cu-spin correlation in the Bi-2201 high-Tc superconductor using muon spin relaxation
Observation of the developed Cu-spin correlation muon spin relaxation
font style='font-size:12px;'>
2010/11/24
A systematic muon-spin-relaxation study in Bi-2201 high-Tc cuprates has revealed for the first
time that the Cu-spin correlation (CSC) is developed at low temperatures below 2 K in a wide
range of h...
Quantum relaxation after a quench in systems with boundaries
Quantum relaxation boundaries
