dc.description.abstractIn this research, we derive a simple expression for the ratio of normal state superconducting state of spin lattice relaxation rate of unconventional superconductors from the BCS weak-coupling equation. The unconventional superconductors we consider have three types of order parameters as d-wave, 3He A-phase and p-wave three-dimensional order parameter that had been done before by Parker and Haas [D. Parker, S. Haas, Physical Review B 75 (2007) 052501]. After using some numerical approximations and some boundary conditions, we can find the ratio of normal state to superconducting state of spin lattice relaxation rate in power series of temperature dependent order parameters and temperature. Our numerical calculations show the coherence peak below critical temperature clearly that are consistent with Parker and Haas [D. Parker, S. Haas, Physical Review B 75 (2007) 052501]. These results do not agree with the believed that the coherence peak is the only property of s-wave superconductor. However from our calculation, we can conclude that the unconventional superconductors can show the coherence peaks. © 2009 Elsevier B.V. All rights reserved.
