Abstract

A magnetothermopower has been observed in electronically spin-polarized polycrystalline and Ba2FeMoO6. The magnetothermopower is linear up to ~50 K for and linear up to ~270 K for Ba2FeMoO6. We suggest that the magnetothermopower may arise from a spin-tunneling magnetothermopower between the grains.
