Ordering particles at the nanometre length scale is a challenging and active research area
in materials science. Several approaches have so far been developed, ranging from the …

Puzzling aspects of high-transition-temperature (high-T c) superconductors include the
prevalence of magnetism in the normal state and the persistence of superconductivity in …

Using 7 Li NMR shift data, the anomalous local moment induced by spinless Li impurities
persists below T c in YBa 2 Cu 3 O 6+ y. In the underdoped regime, the moments retain their …

Nuclear magnetic resonance has emerged as a vital technique for investigating strongly
correlated electron systems, and is particularly important for studying superconductivity. In …

The vortex phase diagram of optimally doped untwinned YBa 2 Cu 3 O y is studied. We find
a first-order transition TL (H) in the vortex liquid above the terminal point H mcp (≃ 7 T) of …

Superconductors have two key characteristics: they expel magnetic field and they conduct
electrical current with zero resistance. However, both properties are compromised in high …

We study a model of ad-wave superconductor with strong potential scatterers in the
presence of antiferromagnetic correlations and apply it to experimental nuclear magnetic …

The magneto-transport properties are systematically measured under c-direction fields up to
33 T for a series of single-crystal films of intercalated iron-selenide superconductor (Li, Fe) …

O 17 NMR is used to probe the local influence of nonmagnetic Zn and magnetic Ni
impurities in the superconducting state of optimally doped high TC YBa 2 Cu 3 O 7. Zn and …

Here, by conducting a site-selective nuclear magnetic resonance (NMR) study on As 75, Cs
133, and F 19 nuclei, we reveal the characteristic dynamics of two-dimensional (2D) …
