Perhaps the Mg intermetallic compound which attracted most interest in the past 10 years is MgB2. The reason for this lies in its superconductivity below 39 K, which is an unusually high value for a phonon-mediated BCS superconductor.139 Soon after the discovery of this phenomenon in March 200...
phase diagrams, superconducting properties, mechanisms, material processing and some newly developingsuperconductor. These would show a strong trait behavior of the high-temperaturesuperconductivitythat has been the subject of intensive study. It has received much attention due to its industrial applications...
9.17.One configuration of a single phase warm dielectric cable. The coolant flows in one direction on the inside of the flexible core tube and in the other direction outside of the superconductor. This arrangement may have a significant counterflow of heat between the two fluid paths, which lim...
(Courtesy of American Superconductor.) BSCCOs are also of two types, the so-called 2:2:2:3 and 2:2:1:2 variants, the numerals referring to the proportions of the constituent elements. The former, seen as having potential applications in bulk superconducting power transformers, motors and ...
mentioned that this experiment can also be performed by using a diamagnetic material such as graphite (Junge 2002).) In this case, due to the very small negative susceptibility of diamagnetic materials, the levitation force is 5–6 orders of magnitude smaller than when a superconductor is ...
Furthermore, in the well-known high-Tc superconductor MgB2, the crystal structure is composed of honeycomb boron plane intercalated by Mg planes. It is believed that superconductivity is originated from the boron plane, while the Mg layers act as electron donor. If the borophene with honeycomb ...
Within this class of compounds, the alkali-doped fullerenes, MgB2 or the highly B-doped diamond and Si-based superconductors are found. Among the Ba-based silicide compounds, it should be noted that only type I Ba-based clathrate compounds and the metastable trigonal phase of BaSi2 (...
Among the variety of magnetic phenomena that may affect the penetration depth we discuss one last subject, the proximityeffect. As is well known, a superconductor in proximity to a normal metal may induce pairing correlations in the normal metal that extend over a distanceζN(de Gennes, 1966)...
It has been shown that superconductivity is of electron–phonon type, and that the lower critical temperature with respect to MgB2 can be understood because the electronic and vibrational states involved in the superconducting pairing are different. CaAl2 is isoelectronic and isostructural to MgB2, ...
