Polycrystalline Morphology and Anomalous Hall Effect in RF-Sputtered Co2MnGa Films
Carter E. Wade, Sunny Phan, Katherine Coffin +5
The Heusler compound Co2MnGa is a topological semimetal with intriguing electronic and magnetic properties, making it a promising candidate for spintronic applications. This study…
Dynamic response of a spin-1/2 Kondo singlet
Bryan Hemingway, Stephen Herbert, Michael Melloch +1
We present a study of spin 1/2 Kondo singlets in single electron transistors under a microwave frequency bias excitation. We compare time-averaged conductance to predicted univ…
A quantitative study of spin-flip co-tunneling transport in a quantum dot
Tai-Min Liu, Anh T. Ngo, Bryan Hemingway +4
We report detailed transport measurements in a quantum dot in a spin-flip co-tunneling regime, and a quantitative comparison of the data to microscopic theory. The quantum dot is f…
Magnetic-Field-Induced Crossover to a Nonuniversal Regime in a Kondo Dot
Tai-Min Liu, Bryan Hemingway, Steven Herbert +2
We have measured the magnetic splitting, , of a Kondo peak in the differential conductance of a Single-Electron Transistor while tuning the Kondo temperature, , along two…
Magnetic Splitting of the Zero Bias Peak in a Quantum Point Contact with a Variable Aspect Ratio
Tai-Min Liu, Bryan Hemingway, Andrei Kogan +2
We report a zero-bias peak in the differential conductance of a Quantum Point Contact (QPC), which splits in an external magnetic field. The peak is observed over a range of device…
Spin polarization control by electric stirring: proposal for a spintronic device
Yu. V. Pershin, N. A. Sinitsyn, A. Kogan +2
We propose a spintronic device to generate spin polarization in a mesoscopic region by purely electric means. We show that the spin Hall effect in combination with the stirring eff…
