Indirect observation of phase conjugate magnons from non-degenerate four-wave mixing
- Abstract:
-
A phase conjugate mirror utilising four-wave mixing in a magnetic system is experimentally realised for the first time. Indirect evidence of continuous-wave phase conjugation has been observed experimentally and is supported by simulations. The experiment utilises a pump-probe method to excite a four-wave mixing process. Two antennae are used to pump a region of a thin-film yttrium iron garnet waveguide with magnons of frequency f1 to create a spatio-temporally periodic potential. As the probe magnons of fp impinge on the pumped region, a signal with frequency fc=2f1−fp is observed. The amplitude of the nonlinear signal was highly dependent on the applied magnetic field H. Width modes of the probe magnons and standing wave modes of the pump magnons were shown to affect the amplitude of the signal at fc . Experimental data are compared with simulations and theory to suggest that fc is a phase conjugate of fp .
