Abstract

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.

磁性 Cu(II) 和非磁性 Ni(II)-(双)草氨酸配合物的核自旋弛豫比较

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。
