论文摘要
我们报告$^{63} $ cu和$^{65} $ cu核自旋宽松放松率的测量值测量氧化乡土的cu $ _2 $ o _2 $ o在零场cu核四极杆共振中以$ = 77 $ = 77 $ - $ 325k。从详细的放宽率估计的限制估计率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率，我们的成功率是我们的成功率。 $^{63} w_m $和主要的核四极杆放松率$^{63} w_q $。 $^{63} w_q $更改为$ t^{2.1} $，而$^{63} w_m $更改为$ t^{1.6} $或$ t^{1.6} $或$ t^β\ mathrm {exp}（exp}（ - \ \itΔ/t）$，带有$β$ = 0.6（3）和$ = 0.6（3）和$ \ itty nondection（62）讨论了费米气体作为磁性松弛的可能候选者。
We report the $^{63}$Cu and $^{65}$Cu nuclear spin-lattice relaxation rate measurements of cuprous oxide Cu$_2$O in a zero field Cu nuclear quadrupole resonance at $T$ = 77$-$325 K. From the detailed isotopic measurements of the relaxation rates, we successfully estimated a finite magnetic relaxation rate $^{63}W_M$ and a predominant nuclear quadrupole relaxation rate $^{63}W_Q$. $^{63}W_Q$ changed as $T^{2.1}$, while $^{63}W_M$ changed as $T^{1.6}$ or $T^β\mathrm{exp}(-\itΔ/T)$ with $β$ = 0.6(3) and $\itΔ$ = 190(62) K. The nuclear spin scattering process due to a non-degenerate Fermi gas was discussed as a possible candidate of the magnetic relaxation.
