The generation of spin voltage by heat, known as the Seebeck effect (SSE), involves injection current from a ferromagnetic to normal metal. In this study, shunting in SSE is investigated within hybrid structure consisting iron (Fe) and cobalt (Co) films deposited on Si-wafer substrate using thermal evaporation [Si/Fe(500 nm)/Co(10 nm)]. Spin measurements performed in-plane configuration revealed reversal Co film Fe film. However, (Si/Fe/Co), signal exhibited consistent directionality. This...

In challenging operational environments such as underground buildings beneath roadways, reliability and performance of wireless power transfer (WPT) systems for electric vehicles (EVs) heavily hinge on the operating temperature magnetic couplers.Addressing this, this study introduces a novel approach employing heat sink thermoelectric cooler technologies to mitigate rise in couplers, which is particularly crucial high-power applications.Utilizing ANSYS simulation, evaluates WPT application...
Spin‐Hall thermopiles have been previously proposed as a means to enhance the spin Seebeck effect (SSE). However, use of platinum (Pt) for detection drives costs high and proves an impediment scalability. In this work, cost‐effective spin‐Hall thermopile constructed from opposite angle ferromagnets, cobalt (Co) iron (Fe), is reported. The devices are fabricated using standard sputter‐coated yttrium garnet (YIG) substrate that serves injector, thermally evaporated Co Fe strips enable...
