In this work, we report measurements of the low-temperature (T ≤ 15K) longitudinal spin Seebeck coefficient (SLSSE) in bulk single crystals of the helimagnetic insulator Cu2OSeO3 with Pt contacts. Simultaneous measurement of both SLSSE and the magnon thermal conductivity (κm) demonstrates their correlation and allows for quantitative and favorable comparison to bulk magnon spin current theory.
