Researchers at UC Riverside created a chip that generated spin wave between transmitting and receiving antennae. They showed that the low-frequency noise of magnonic devices is dominated by the random telegraph signal noise rather than 1/f noise. It was also found that the noise level of surface magnons depends strongly on the power level, increasing sharply at the on-set of nonlinear dissipation. The presence of the random telegraph signal noise suggests that the current fluctuations involve random discrete macro events caused by an individual macro-scale fluctuator. The findings may help in developing the next generation of magnonic devices for information processing and sensing…read more. Open Access TECHNICAL ARTICLE
