概要
- 論文の詳細を見る
We report the ^<75>As nuclear magnetic resonance (NMR) measurement of the hole-doped superconductor Ba_<1-x>K_xFe_2As_2 with different lattice parameters and different superconducting volume fractions (T_cc≃38K). ^<75>As-NMR spectra revealed that the magnetically ordered and superconducting phases are microscopically separated. The spin-lattice relaxation rate 1/T_1 in the normal state reflects the existence of a large two-dimensional antiferromagnetic spin fluctuation. The 1/T_1 in the superconducting state down to the lowest measurement temperature T varies close to T^3. In addition, it exhibits no coherence peak just below T_c. This shows a T dependence similar to those of other iron pnictides.
