From: Realization of a micrometre-scale spin-wave interferometer

Maps of interferences at 75 mT.
The sample is the same as that described in Fig. 2(a). The real part of the transmission between antennas 1 and 2 (Re S21) for different frequencies and applied Idc are shown in (a) and the imaginary part (Im S21) in (b). The phase because of spin-wave transmission detected by antenna 2 is presented in (c).
