Abstract

Possible new superconducting phases with a high critical transition temperature (Tc) have been found in stable palladium-hydrogen (PdHx) samples for stoichiometric ratio x = H/Pd ≥ 1, in addition to the well-known low critical transition temperature (0 ≤ Tc≤ 9) when x is in the range (0.75 ≤ x ≤ 1.00). Possible new measured superconducting phases with critical temperature in the range 51 ≤ Tc≤ 295 K occur. This Tcvaries considerably with every milli part of x when x exceeds unit. A superconducting critical current density Jc≥ 6.1 × 104A cm-2has been measured at 77 K with HDC= 0 T. © 2003 Elsevier Science B.V. All rights reserved.
