History of superconductivity also be used i.e. the spinel battery material LiTi2Ox and the lattice pressure can increase Tc to over 13.8K Also LiHx has been theorized to metallise at a substantially lower pressure than H and could be a candidate for a Type 1 superconductor. Papers by H.K. Onnes BCS theory Other key papers Patents History of superconductivity Superconductivity is the phenomenon of certain materials exhibiting zero electrical resistance and the expulsion of magnetic fields below a characteristic temperature. The history of superconductivity began with Dutch physicist Heike Kamerlingh Onnes's discovery of superconductivity in mercury in 1911. Since then, many other superconducting
Weiss magneton of the saturation magnetization at the temperature of liquid hydrogen in the laboratory of Heike Kamerlingh Onnes in Leiden. In 1911, Weiss announced that the molar moments of nickel and iron had the ratio of 3:11, from which he derived the value of a magneton. Weiss gave an address about the magneton at a conference in Karlsruhe in September 1911. Several theorists commented that the magneton should involve Planck's constant "h". By postulating that the ratio of electron kinetic energy to orbital frequency should be equal to "h", Richard Gans computed a value that was almost an order of magnitude
