We find also a second second-order phase transition. As temperature is lowered-past the usual critical temperature T-c, a less ordered superconducting phase is created in the d wave, which changes to a more ordered phase in a (s + id) wave at T-c1 (<T-c). The presence of two phase transitions is manifested by the two jumps in the specific heat at T-c and T(c)1. The temperature dependencies of the susceptibility, penetration depth, and thermal conductivity also confirm the existence of the new phase transition.L319-L325engCarta10.1088/0953-8984/10/20/002WOS:000074084900002Acesso aberto8031087349809439
