    Welcome to SUPERCONDUCTORS. My name is Joe Eck. I am the author of these web pages. I have been an electronics engineer since leaving college in and superconductors are a passion of mine. I study them and regularly experiment with esoteric concoctions as part of the search for new high-Tc compounds. Among my accomplishments are the. Iron-based superconductors are considered to be important for understanding high temperature superconductivity from a new perspective due to the presence of a high superconducting critical temperature (T c) that cannot be explained within the framework of conventional phonon-mediated BCS er, the electronic states of the parent compounds and the superconducting Cited by: 11 B and Pt NMR studies in the normal state of substituted borocarbide superconductors Y Er Ni 2 B 2 C and LaPt Au B 2 C K. Elankumaran K, A.V. Mahajan, L.C. Gupta, Z. Hossain, R. Nagarajan, R. Vijayaraghavan R, Physica B () High pressure study of borocarbide superconductor YNi 2 B 2 C at room temperature. The discovery of “high-temperature” superconductors in the s — materials that could lose resistance at temperatures of up to negative degrees Celsius — led to speculation that a surge of new discoveries might quickly lead to room-temperature superconductors. Despite intense research, these materials have remained poorly understood.

The rationale was the BCS Tc-formula [8] where a high characteristic phonon frequency, as provided by the light boron atoms, was predicted to be particularly helpful with respect to a high Tc. In the s, the borocarbide superconductors RE Ni2B2C with Tc up to K [19] seemed to fulfill this promise at least halfway.
