| For an ferromagnetic insulator (FI) and normal metal (NM) bilayer structure, we predict theoretically that due to magnetic fluctuations, a longitudinal (parallel to equilibrium magnetization) spin current can be injected into a normal metal by applying i) a magnetic field, ii) a spin accumulation in the NM, both parallel to the magnetization, or iii) a temperature difference across the interface. In addition to the previously studied spin Seebeck effect, we find several other previously unknown effects including the recently discovered spin Peltier effect, in which a longitudinal spin accumulation heats up or cools down the magnetization. An Onsager matrix revealing all effects has been identified. |
