Spin wave, or its quanta magnon, is expected to be an efficient information carrier flowing in an insulating media alternative to electrical charge current that has Joule loss. To realize functional magnonic circuits, non-linear transport behavior of magnons is essential considering that semiconductor diodes revolutionized our society. In fact, magnons do show such behavior, however it suffers from an intrinsic limitation, i.e., a saturation of non-linear growth of magnon transconductance due to magnon-magnon scattering process, as we reported in the previous JSPS meeting (19a-A201-2). Using non-local devices consisting of two parallel Pt electrodes deposited on (Bi-doped) YIG films, we experimentally report two times more enhancement of non-linear growth of magnon transconductance in a Bi-doped YIG with a perpendicular anisotropy compared to that in a normal YIG.
