[In Russian. / En russe.]

Author(s) : ANCYGINA T. N., SLJUSAREV V. A.

Type of article: Article

Summary

THE TEMPERATURE DEPENDENCES OF THE ORDER PARAMETER AND THE ENERGY GAP OF HIGH CRITICAL TEMPERATURE SUPERCONDUCTORS ARE STUDIED USING THE SPECIFIC GEOMETRY OF THE CUO(2) PLANE. IT IS SHOWN THAT THE EFFECTS OF CARRIER SCATTERING BY THE SPIN FLUCTUATIONS OF THE COPPER SUBSYSTEM PRODUCE NO ESSENTIAL INFLUENCE UPON THE BEHAVIOUR OF THE ORDER PARAMETER THOUGH LEAD TO A SHARP DECREASE OF THE ENERGY GAP IN THE EXCITATION SPECTRUM. WITH A CERTAIN CORRELATION OF THE SYSTEM PARAMETERS, GAPLESS SUPERCONDUCTIVITY MAY EXIST IN THE WHOLE RANGE OF TEMPERATURES.
