Magnon Spin Current Modulation through Site-Specific Doping in a Compensated Iron Garnet

Anna Merin Francis, P. B. S. Murthykrishnan, Ratnamay Kolay +2

We report on the impact of manganese doping at the iron sites in Gadolinium Iron Garnet (GdIG, Gd${}_3$Fe${}_5$O${}_{12}$), employing temperature-dependent spin Seebeck effect and fe…
