N2 - A magnetic-field sensor with a high sensitivity of 38 pT/Hz was demonstrated. By utilizing a spin-wave differential circuit (SWDC) using two yttrium iron garnet (YIG) films, the temperature sensitivity was suppressed, and the thermal stability of the phase of the spin waves was -0.0095° K-1, which is three orders of magnitude better than a simple YIG-based sensor, ∼20° K-1. The SWDC architecture opens the way to design YIG-based magnonic devices.
