CaWO\(_4\):Gd\(^{3+}\). (a) Rabi oscillations shown as the real and imaginary part of the recorded signal (blue and orange lines, respectively). From left to right, the initial (and final) state of the spin are \(+X\), \(+Y\) and \(+Z\). After a time given by an integer number of Rabi flops, shown with an arrow in the inset, (b) the spin-echo signal is recorded for each spin component, using the measurement sequence described in Fig. 3.
