Experimental Observation of a Possible First-Order Phase Transition below the Superconducting Transition Temperature in the Multilayer Cuprate Superconductor HgBa 2 Ca 4 Cu 5 O y
/ Authors
/ Abstract
A hysteretic specific heat jump at approximately 41 K is found experimentally in the multilayer cuprate superconductor HgBa2Ca4Cu5Oy (Hg-1245), with a superconducting transition temperature of 108 ...
