The phase diagram of the filled skutterudite CeOs4Sb12 has been mapped in fields μ0H of up to 60 T and temperatures T down to 0.5 K using resistivity, magnetostriction, and megahertz conductivity. The valence transition separating the semimetallic…
We report the results of a muon spin relaxation study of slow magnetic fluctuations in the pseudogap phase of underdoped single-crystalline YBa2Cu3Oy,y=6.77 and 6.83. The dependence of the dynamic muon spin relaxation rate on applied magnetic field…
