Muon-spin-rotation study of vortex states in RBa2Cu3O7 using maximum-entropy analysis
Abstract
A maximum-entropy method has been applied to transverse-field muon-spin-rotation vortex data of RBa2Cu3O7 (R 1:2:3:7; R=Er, Gd, and Eu); this produces spectra representing estimates for the magnetic-field distributions. The information on the field distribution is of better quality than that resulting from Fourier transformation and curve fitting of the same data. Significant deviations from Abrikosov predictions have been observed for the estimated R 1:2:3:7 vortex-field distributions. Below 10 K, for Er 1:2:3:7 and Gd 1:2:3:7, the non-Abrikosov features appear to be influenced by the magnetism of the rare-earth layers.
