چکیده
We perform a quantitative, comparative study of the spin pumping, spin Seebeck, and spin Hall magnetoresistance effects, all detected via the inverse spin Hall effect in a series of over 20 yttrium iron garnet/Pt samples. Our experimental results fully support present, exclusively spin current-based, theoretical models using a single set of plausible parameters for spin mixing conductance, spin Hall angle, and spin diffusion length. Our findings establish the purely spintronic nature of the aforementioned effects and provide a quantitative description, in particular, of the spin Seebeck effect.

Spin Seebeck effect and spin Hall magnetoresistance at high temperatures for a Pt/yttrium iron garnet hybrid structure.
Based on unique experimental setups, the temperature dependences of the longitudinal spin Seebeck effect (LSSE) and spin Hall magnetoresistance (SMR) of the Pt/yttrium iron garnet (Pt/YIG) hybrid structure are determined in a wide temperature range up to the Curie temperature of YIG. From a theoretical analysis of the experimental relationship between the SMR and temperature, the spin mixing co...
متن کاملStudy of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...
متن کاملEffect of interfacial species mixing on phonon transport in semiconductor superlattices
Molecular dynamics simulations are used to examine the effect of interfacial species mixing on the thermal conductivity of Stillinger-Weber Si /Si0.7Ge0.3 and Si/Ge superlattices at a temperature of 500 K. The thermal conductivity of Si /Si0.7Ge0.3 superlattices is predicted to not depend on the interfacial species mixing and to increase with increasing period length. This period length depende...
متن کاملExperimental Studies and Cfd Calculations for Buoyancy Driven Mixing Phenomena
Buoyancy driven flow is found in many engineering application such as the mixing of fluids with different densities. In nuclear reactor safety the mixing of borated and deborated water is a critical issue that needs investigation, assessment and prediction. As nuclear reactor geometries are complex, in this study a simple vertical mixing test facility (VeMix) was used to validate numerical mode...
متن کاملSpin crossover in ferropericlase from first-principles molecular dynamics.
Ferropericlase, (Mg,Fe)O, is the second-most abundant mineral of Earth's lower mantle. With increasing pressure, the Fe ions in the material begin to collapse from a magnetic to nonmagnetic spin state. We present a finite-temperature first-principles phase diagram of this spin crossover, finding a broad pressure range with coexisting magnetic and nonmagnetic ions due to favorable enthalpy of mi...
