Data set for Tuning the magnon transport properties of Y3Fe5O12 with a cobalt phthalocyanine layer

The dataset file includes:

Figure 1 shows the nonlocal device structure of YIG with a CoPc molecular overlayer and the angle-dependent local resistance.

Figure 2 presents the nonlocal voltages of devices with and without a CoPc overlayer.

Figure 3 displays the FMR frequency measurements of the pristine YIG film and YIG with a CoPc layer.

Figure 4 shows the nonlocal voltage amplitude, normalized to the applied current, as a function of injector–detector distance for electrically generated magnon currents in the devices.

Figure 5 presents the measured FMR linewidths and the fitted Gilbert damping constants of YIG/CoPc and pristine YIG structures.

The supporting figures are as follows:

Figure S1 shows the nonlocal voltage amplitude versus applied current for both electrically and thermally excited magnon currents in devices with and without a CoPc overlayer.

Figure S2 displays the field-dependent nonlocal signal for electrically excited magnon currents in devices with and without a CoPc overlayer in the high-field regime.

Figure S3 presents the field-dependent nonlocal signals for electrically excited magnon currents in devices with and without a CoPc layer at different temperatures.

Figure S4 shows the field-dependent nonlocal signal for thermally excited magnon currents in devices with and without a CoPc overlayer in the high-field regime.

Figure S5 shows the measured FMR spectra of pristine YIG and YIG/CoPc structures as a function of frequency.

Figure S6 presents the thermally excited nonlocal magnon currents in devices with and without a CoPc overlayer as a function of injector–detector distance.
