To realize magnonic devices, finding a way to make magnons better transport and efficiently pump their spin angular momentum across a ferromagnetic insulator (FMI)/normal metal interface is crucial. An international team of researchers (South Korea, Japan) found that modulating the magnon temperature in the FMI led to significantly enhanced spin pumping. The modulation was achieved by careful interfacial engineering via a nanoscale thermal fin structure that strengthened the energy exchange between magnons and phonons across interfaces. Theoretical and experimental evidence coherently indicated that the observed enhancement was due to modified magnon temperature profile in the FMI. According to the researchers their discovery provides a versatile thermal route to manipulate the magnon spin current and may contribute to developing practical magnonic devices… read more.
