Small angle neutron scattering studies of the flux line lattice (FLL) in UPt3 for fields H⊥c provide direct microscopic evidence for the 5 kOe B→C transition. We find a pronounced maximum in the longitudinal correlation length of the FLL at the t

Small-angle neutron scattering and magnetic decoration both demonstrate a topological transition in the flux line lattice (FLL) in ErNi{sub 2}B{sub 2}C. The high-field square lattice slowly transforms into a hexagonal lattice via an area preserving [

Samples of Y1−x Ca x Sr2GaCu2O7−δ (x=0, 0.4) doped with57Fe, prepared under various oxygen pressures, have been studied by magnetometry and Mossbauer spectroscopy. Most of the iron ions (Fe3+) enter the Ga(Cu(1)) site. For thex=0 sample, the Mos
