TL;DR: In this paper, angular-resolved photoemission experiments on high-temperature superconductors are consistent with a phenomenological description of the normal state of these materials as marginal Fermi liquids.
Abstract: Recent angular-resolved photoemission experiments on high-temperature superconductors are consistent with a phenomenological description of the normal state of these materials as marginal Fermi liquids. The experiments also provide constraints on microscopic theories.

TL;DR: In this paper, the magnetic pattern of YBa(2)Cu(3)O(6.35) superconductors was analyzed and the role of striped phases was clarified.
Abstract: Neutron scattering has been used to measure the charge and spin structure in the highly underdoped superconductor YBa(2)Cu(3)O(6.35). Incommensurate static charge ordering is found that remains at high temperatures. The magnetic pattern is complex with a resonance and incommensurate structure observed at low temperatures. The results clarify the role of striped phases in YBa(2)Cu(3)O(6+x) superconductors.

TL;DR: In this paper, a detailed calculation of the surface impedance of superconductors is given based on the general theory of the anomalous skin effect in normal and superconducting metals given by Mattis and Bardeen.
Abstract: A detailed calculation of the surface impedance of superconductors is given based on the general theory of the anomalous skin effect in normal and superconducting metals given by Mattis and Bardeen. It is found that there are large corrections to the extreme anomalous limit value of the superconducting to normal surface resistance ratio; corrections to the surface reactance ratio are much smaller. The theory is compared with recent experiments on the surface impedance of aluminum and of tin. It is found that the theory gives satisfactory agreement with experimental data on the surface impedance, both in absolute value and in its temperature and frequency dependence over a wide range of temperatures and frequencies.

TL;DR: In this paper, the authors reported the discovery of a new class of superconductors, LixNbO2 with layered structures, which showed that at low applied magnetic fields, the magnetic susceptibility greatly decreases to diamagnetic values below 5.5 K.
Abstract: SEVERAL classes of copper oxide compounds are high-temperature superconductors1–3; the highest known transition temperature (Tc) is 122 K for Tl2Ba2Ca2Cu3O11 (ref. 4). Superconductivity has also been observed in oxides containing early transition metals, but the superconducting transition temperatures are substantially lower. (The highest known Tc for an early transition metal oxide is 13.7 K, for the spinel compound LiTi2O4 (ref. 5).) Whereas all of the copper oxide superconductors have very anisotropic structures, the superconducting oxides of early transition metals discovered up to now have three-dimensional structures. Here we report the discovery of a new class of superconductors, LixNbO2 with layered structures. At low applied magnetic fields, the magnetic susceptibility greatly decreases to diamagnetic values below 5.5 K for Li0.45NbO2 and below 5.5 K for Li0.45NbO2; this transition indicates the onset of superconductivity. In this first example of superconductivity in a layered early transition metal oxide, it is interesting to note that the layering has not increased Tc to new levels for early transition metal oxides.
