摘要

摘要分子磁体的电子系统有望用于量子计算设备。磁共振技术可用于磁化操纵和相干跟踪。采用不同的脉冲方案，利用 1H NMR 技术研究了[n-Bu4N]2[Cu(opba)]和[n-Bu4N]2[Ni(opba)]复合物。结果表明，脉冲间延迟移动和相位循环方法适用于 1H NMR，但其效率不如 EPR。由于许多核位置完全抑制了不需要的回波贡献，因此应考虑包括纵向磁化演化在内的子总体。

Comparison of the Nuclear Spin Relaxation in Magnetic Cu(II) and Nonmagnetic Ni(II)-(bis)oxamato Complexes

The electronic system of molecular-based magnets is promising for use in quantum computing devices. Magnetic resonance techniques are used for magnetization manipulation and coherence tracking. The complexes [n-Bu₄N]₂[Cu(opba)] and [n-Bu₄N]₂[Ni(opba)] have been studied by ¹H NMR technique using different pulse protocols. It is shown that the interpulse delay shift and phase cycling approaches are applicable in ¹H NMR, but it’s not as efficient as they are in EPR. Since many nuclei positions completely suppress the unwanted echo contribution, the subensembles including the longitudinal magnetization evolution should be considered.
