The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Observation of spin Seebeck contribution to the transverse thermopower in Ni-Pt and MnBi-Au bulk nanocomposites

Nature Communications, 2016
The spin Seebeck effect enables thermal-to-electrical energy conversion but the power generated in thin films remains low. Here, Boonaet al. use composites of ferromagnetic conductors containing noble metal nanoparticles to show that the effect can ...

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Designer Entropy Enables High Thermoelectric Power and Efficiency

Interdisciplinary Materials, EarlyView.
Designer Entropy enables targeted control of defect and transport behavior in SnTe‐based alloys, allowing efficiency and power to be independently optimized. Radius‐matched Sb doping preserves carrier mobility and delivers superior power output, while Bi‐induced disorder suppresses mobility despite comparable efficiency.

Spin Seebeck effect of interacting spinons

Physical Review B
We present the theory of the longitudinal spin Seebeck effect between a Heisenberg spin-1/2 chain and a conductor. The effect consists of the generation of a spin current across the spin chain-conductor interface in response to the temperature difference between the two systems.
