Enhancement of spin seebeck effect of reverse spin crossover fe (ii) micellar charge transport using PMMA polymer electrolyte

The electrochemical thermoelectric effect is capable of generating Seebeck and conductivity from a temperature gradient through redox reaction at the electrode. Conventional spin Seebeck effect (SSE) is the generation of spin voltage by solid coupling magnetic thin film in presence of magnetic field...
