Abstract

Transport and thermodynamical properties as well as structural investigations in the well-characterized 90 K-class high-T_c superconductor YBa₂Cu₃O₇ are presented, especially in relation to the fundamental mechanism of the high-T_c superconductivity. High-precision specific heat measurements around T_c=91.8 K reveal that the value of ΔC/T_c is 48±2 mJ/mol K². This value results in the fact that the value of ΔC/γT_c is 1.33, which is close to 1.43, the weak-coupling BCS value, provided that the coefficient, γ, of the linear term in the specific heat is 36±2 mJ/mol K².
