Description |
627-632
The transition temperature <i style="">T</i><sub>C</sub> and the specific heat jump ∆<i style="">C</i>/<i style="">T<sub>C</sub></i> in La<sub>2</sub><sub>-x</sub>Ba<sub>x</sub>CuO<sub>4, </sub>Bi<sub>2</sub>Ca<sub>n</sub><sub>-1</sub>Sr<sub>n</sub>Cu<sub>n</sub>O<sub>2n+4</sub> and Tl<sub>2</sub>Ca<sub>n</sub><sub>-1</sub>Ba<sub>2</sub>Cu<sub>n</sub>O<sub>2n+3(2n+4)</sub> are calculated using exotic pairing model. These values are calculated at both buckling mode and breathing mode. The values calculated are compared with known experimental values. If ∆ is the gap in the allowed energy states, then the jump in the specific heat is C<sub>S</sub>-C<sub>n</sub>. These results show that the calculated values of the ratios and <i style="">T</i><sub>C</sub> compare well with experimental values. |
