We have observed the spatial distribution of magnetic flux in Nb, Cu/Nb and Cu/Nb/Co thin films using muon-spin rotation. In an isolated 50 nm thick Nb film we find a weak flux expulsion (Meissner effect) which becomes significantly enhanced when add

Thanks to the high quality single crystals of MgB2, we have measured various physical properties to extract important features of the electronic state in this superconductor. The electron density maps calculated from a precise X-ray diffraction analy

The average value of the magnetocrystalline anisotropy field, Hk, is an important parameter for the characterization of magnetic recording media but is difficult to measure accurately due in part to the effect of interactions between the grains. In o

We have measured the diffracted neutron scattering intensities from the square magnetic flux lattice in the perovskite superconductor ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$, which is thought to exhibit $p$-wave pairing with a two-component order param

We have carried out angle resolved photoemission spectroscopy of ${\mathrm{SmTe}}_{3}$, a quasi-two-dimensional material with an incommensurate high-temperature charge density wave (CDW). This is the first direct experimental view of the full detail

Muon spin rotation ({mu}SR) measurements have been performed on the organic superconductor {kappa}-(BEDT-TTF){sub 2}Cu(SCN){sub 2} in order to investigate its exotic vortex behavior. Previously unobserved features of the {mu}SR line shapes have been

Muon-spin rotation measurements, performed on the mixed state of the classic anisotropic superconductor Bi2:15Sr1:85CaCu2O8þ� , obtain quantities directly related to two- and three-body correlations of vortices in space. A novel phase diagram emer

The response of the superconducting charge carriers to an applied magnetic field has been probed in a number of organic superconductors using μSR. Systematic studies have been made of the in-plane superconducting penetration depth λ in superconduct

In the mixed state of ${\mathrm{Bi}}_{2.15}{\mathrm{Sr}}_{1.85}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ the temperature dependence of the muon spin rotation ( $\ensuremath{\mu}\mathrm{SR}$) linewidth is found to have a strong field de

A flux‐line lattice (FLL) was observed in a single crystal of Bi2.15Sr1.95CaCu2O8+x (BSCCO) using small‐angle neutron scattering methods. The sample has a superconducting transition at 85 K. The flux‐line lattice is observed to melt, evidenced
