我们研究了作为电子自旋寿命限制因素的Er触发器动力学,更广泛地说,它是稀土掺杂绝缘体中退相干的间接来源。尽管掺杂在主体晶体中呈随机各向同性排列,但偶极相互作用强烈地依赖于磁场取向,并伴随着g因子的强各向异性。在Er~(3+):Y~(3+):Y~(2+)SiO_5~(5)晶体中,我们用瞬变光谱学观察到Er的触发率(10ppm掺杂浓度)有三个数量级的变化。在浓度为10ppm和50ppm的两个不同样品中的测量,得到了我们对具有各向异性$g$张量的相同自旋之间的偶极耦合的解析模拟的很好支持。该模型也适用于其他稀土掺杂材料。我们将计算外推到不同浓度下的Er^^{3+}$:CaWO$4$,Er$^{3+}$:LiNbO$3$和Nd^^{3+}$:Y$2$SiO$5$。
We investigate the erbium flip-flop dynamics as a limiting factor of the electron spin lifetime and more generally as an indirect source of decoherence in rare-earth doped insulators. Despite the random isotropic arrangement of dopants in the host crystal, the dipolar interaction strongly depends on the magnetic field orientation following the strong anisotropy of the $g$-factor. In Er$^{3+}$:Y$_2$SiO$_5$, we observe by transient optical spectroscopy a three orders of magnitude variation of the erbium flip-flop rate (10ppm dopant concentration). The measurements in two different samples, with 10ppm and 50ppm concentrations, are well-supported by our analytic modeling of the dipolar coupling between identical spins with an anisotropic $g$-tensor. The model can be applied to other rare-earth doped materials. We extrapolate the calculation to Er$^{3+}$:CaWO$_4$, Er$^{3+}$:LiNbO$_3$ and Nd$^{3+}$:Y$_2$SiO$_5$ at different concentrations.
