The structure's of the flux-line lattice and of individual vortices on the surface of a uniaxial anisotropic superconductor 2H-${\mathrm{NbSe}}_{2}$ are studied for arbitrary magnetic fields using the scanning tunneling microscope. The basis vectors

Measurement of the response of the flux-line lattice in NbSe2 and La1.825Sr0.075CuO4 show important differences between these two materials. In particular, we have studied the magnetic-field and angular dependence of the response of a high-Q mechanic

We report on observations of the magnetic flux lattice in 2H-NbSe 2 using the magnetic decoration technique. For low applied magnetic fields and with the field applied parallel to the c axis of the crystal, we find a disordered flux lattice with shor

63 Cu(2) NMR linewidths in Zn-doped YBa 2 Cu 3 O 7 exhibit a predominant component proportional to T -1 in the normal state. We attribute this result to spin-exchange scattering of carriers from localized moments associated with Zn impurities in the

The YCuO2 and LaCuO2 delafossites consist of alternating triangular planes of Ln3+ octahedra and O -Cu1+-O sticks. Here it is shown that under a limited set of conditions they may be oxidized to form new delafossite-derived phases YCuO2.5+x, 0 ≤ x

Single crystals of the reduced niobate Ba2Nb15O32 are produced by heating NbO2 in BaO·3B2O3 under high-vacuum conditions. The borate acts both as a source of BaO and as a flux for crystallization. The compound Ba2Nb15O32 crystallizes in space group

A series of double perovskites Ba{sub 2}MBiO{sub 6} (M=Ce to Lu) was prepared and characterized chemically and by powder X-ray diffraction. Crystal structures of Ba{sub 2}MBiO{sub 6}(M = Ce, Pr, Nd, Tb, Yb) were determined by neutron diffraction and
