We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In presence 3% hydrogen gas, SSE voltage decreases more than 50% from magnitude observed pure Ar gas. The is reversible, but recovery to prehydrogenation value takes a few days because long time constant desorption. also that Hall magnetoresistance identical sample reduces significantly with exposure...

In 1822, Thomas Seebeck, an Estonian physician, accidentally joined semicircular pieces of bismuth and copper (Figure 1) while studying thermal effects on galvanic arrangements. A nearby compass indicated a magnetic disturbance. Seebeck experimented repeatedly with different metal combinations at various temperatures, noting relative magnetic fi eld strengths. Curiously, he did not believe that...

In this paper we investigate the spin-resolved thermoelectric properties of strongly correlated molecular junctions in linear response regime. The magnetic molecule is modeled by a single orbital level to which core spin attached an exchange interaction. Using numerical renormalization group method analyze behavior (spin) Seebeck effect, heat conductance and figure merit for different model par...
