TL;DR: In this paper, a traveling-solvent floating-zone (TZF) sample was used to grow a superconducting sample with a large inhomogeneity in structural and physical properties, such as lattice parameters and transport and magnetic properties.

TL;DR: It is shown in Fe/Cu bilayered films that the magneto-optical polar Kerr rotation can be enhanced by an effect of the plasma resonance of the free charge carriers in Cu.

TL;DR: In this paper, an experimental manifestation of how the singleparticle density of states around the Fermi level changes near a Mott transition was presented, where the spectral weight of the coherent band near the Mott-Hubbard system was gradually transferred to the precursor of the lower Hubbard band and the momentum dependence of the quasiparticle self-energy and hence the long-range exchange or correlation was progressively important.

TL;DR: In this paper, an anomalous long Cu-O (planar) distance, 196 \AA{, assigned to distorted strips of width W intercalated with undistorted stripes of width L, was measured by polarized Cu K-edge extended x-ray-absorption fine structure at T${\mathit{T}}_{\Mathit{c}}$

TL;DR: The relation between the critical temperature T c and the carrier density n is comparable with those previously observed in Nb-doped or reduced SrTiO 3 systems as discussed by the authors, and the apparent universality of the relation suggests that T c in the doped SRTiO3 system is predominantly determined by n and independent of the method of doping.
