我们测量了YNi2B2C (Tc=13.8K)生长单晶在超导状态下至0.9K时的自旋-晶格弛豫率1/T1, 1/T1在T以下没有Hebel-Slichter峰,在T3时急剧下降,随后在低温时1/T1∝T缓慢依赖。在t1结果的基础上讨论了配对状态。
We have measured the spin-lattice relaxation rate 1/T1in an as-grown single crystal of YNi2B2C (Tc=13.8K) in the superconducting state down to 0.9K. 1/T1shows no Hebel–Slichter peak just below T, decreasing sharply as T3, and followed by a slow dependence of 1/T1∝T at low temperatures. The pairing state is discussed on the basis of T1result.
