TL;DR: In this paper, the temperature dependence of the linewidth in the superconducting state follows a trend expected from NMR measurements in superconductors, and the ESR of Gd in CeRu2 and LaRu2 has been observed in the normal and super-conducting states.

TL;DR: In this paper, theoretical work on the electron (exciton) mechanism of superconductivity in three-dimensional systems, which leads to high critical temperatures, is described and discussed in the case of uniform and granulated systems.
Abstract: The article describes theoretical work on the electron (exciton) mechanism of superconductivity in three-dimensional systems, which leads to high critical temperatures. Two models are considered: 1) systems with collective electrons of one group and localized electrons of another group (compounds of metals with dielectrics, organic substances, semiconductors or molecular crystals); 2) systems with two (or more) groups of collective electrons (metals with overlapping bands and multi-domain semiconductors). In the first case, uniform and granulated systems are considered. The effect of the critical fluctuations impeding the superconductivity is discussed in the case of granulated systems. Experimental work on the superconductivity of compounds of metals with dielectrics, organic substances, semiconductors and semimetals is described and discussed.

TL;DR: The first direct evidence for spontaneous spin order below Tc, the superconducting transltion temperature, was provided by as discussed by the authors, who used the Mossbauer effect of 57Fe as a dilute impurity probe to observe the presence of magnetic spin order.
Abstract: We have used the Mossbauer effect (ME) of 57Fe as a dilute impurity probe to observe the presence of magnetic spin order in materials that are also superconducting.1 These measurements provide the first direct evidence for spontaneous spin order below Tc, the superconducting transltion temperature.
TL;DR: In this paper, the author believes a recent letter by Passow contains several inconsistent and misleading statements, and he believes that Passow's recent letter contains several inconsistencies and misstatements.

TL;DR: In this article, a measurement of the phonon line width of strong coupling superconductors by inelastic neutron scattering can be used to detect parallel parts in the Fermi surface of the metal.
TL;DR: In this article, an explanation for the anomaly that has been observed in the mixed to normal state specific heat discontinuity of type II superconductors in low fields, near T c, was suggested.
