Spin pumping and inverse spin Hall voltages from dynamical antiferromagnets

Øyvind Johansen and Arne Brataas

Phys. Rev. B 95, 220408(R) (2017) - Published 20 June, 2017

The real benefit of antiferromagnets is that they can enable terahertz spintronic circuits. Spin pumping is a versatile tool for generating pure spin currents and probing spin dynamics. The high antiferromagnetic resonance frequencies represent a challenge for experimental detection, but magnetic fields can reduce these resonance frequencies. The authors compute the inverse spin Hall voltages resulting from dynamical spin excitations. They suggest practical opportunities that will significantly enhance the spin pumping and inverse spin Hall voltage for the uniaxial antiferromagnets MnF2 and FeF2.

Nanoscale thermoelectrical detection of magnetic domain wall propagation

Patryk Krzysteczko, James Wells, Alexander Fernández Scarioni, Zbynek Soban, Tomas Janda, Xiukun Hu, Vit Saidl, Richard P. Campion, Rhodri Mansell, Ji-Hyun Lee, Russell P. Cowburn, Petr Nemec, Olga Kazakova, Joerg Wunderlich, and Hans Werner Schumacher

Phys. Rev. B 95, 220410(R) (2017) - Published 27 June, 2017

The authors demonstrate a novel ultrahigh-resolution, minimally invasive technique for the detection of the domain-wall position within magnetic nanostructures. Based on the anomalous Nernst effect, the technique is suitable for a wide range of spintronic nanodevices implementing perpendicular-anisotropy materials. A thermal gradient generated on-chip is used to drive charge carriers, which are in turn deflected by the sample’s magnetization. Domain-wall positions within the device can be monitored with a resolution of 20 nm by measurement of the resulting Nernst voltages.

Ballistic magnon heat conduction and possible Poiseuille flow in the helimagnetic insulator Cu2OSeO3

N. Prasai, B. A. Trump, G. G. Marcus, A. Akopyan, S. X. Huang, T. M. McQueen, and J. L. Cohn

Phys. Rev. B 95, 224407 (2017) - Published 5 June, 2017

Low-temperature thermal conductivity measurements in the ferrimagnetic insulator Cu2OSeO3 reveal an unprecedentedly large magnonic contribution below T~10K, far exceeding (by nearly two orders of magnitude) that observed previously in any other ferromagnet or ferrimagnet. Features predicted by theory more than 50 years ago are identified, including ballistic behavior with κmT2, and, possibly, Poiseuille flow, wherein the magnon mean-free path exceeds the specimen dimensions as momentum conserving scattering occurs more frequently than scattering by resistive processes.

Thermoelectric effects in superconductor-ferromagnet tunnel junctions on europium sulfide

S. Kolenda, C. Sürgers, G. Fischer, and D. Beckmann

Phys. Rev. B 95, 224505 (2017) - Published 7 June, 2017

Thermoelectric effects can be surprisingly large in superconductor-ferromagnet tunnel junctions when the superconductor is subject to a spin-splitting field. The spin splitting can be provided by an applied magnetic field, but can also be created by exchange coupling to a ferromagnetic insulator. Here, it is shown that thermoelectric effects in superconductor-ferromagnet tunnel junctions can be enhanced by boosting the spin splitting with an intrinsic exchange field provided by a ferromagnetic insulator. These findings could lead to more precise local electron thermometry or efficient microrefrigerators.

Fermi-surface transformation across the pseudogap critical point of the cuprate superconductor La1.6xNd0.4SrxCuO4

C. Collignon, S. Badoux, S. A. A. Afshar, B. Michon, F. Laliberté, O. Cyr-Choinière, J.-S. Zhou, S. Licciardello, S. Wiedmann, N. Doiron-Leyraud, and Louis Taillefer

Phys. Rev. B 95, 224517 (2017) - Published 29 June, 2017

After two decades of intense investigation, the pseudogap phase of cuprate superconductors still remains a puzzle. The authors explore it by measuring the electrical resistivity and Hall coefficient of the cuprate Nd-LSCO in high magnetic fields for closely spaced doping rates across the pseudogap critical point. They report two main observations. First, both types of measurement indicate a drop of carrier density from 1+p to p upon entering the pseudogap phase; the process is best characterized as a crossover as a function of temperature at fixed doping and as a transition as a function of doping at zero temperature. Second, the mobility is unaffected by the transition. These findings, quantitively consistent with the cases of YBCO and LSCO, appear to be a universal signature of the pseudogap.

Thermoelectric effects can be surprisingly large in superconductor-ferromagnet tunnel junctions when the superconductor is subject to a spin-splitting field. The spin splitting can be provided by an applied magnetic field, but can also be created by exchange coupling to a ferromagnetic insulator. Here, it is shown that thermoelectric effects in superconductor-ferromagnet tunnel junctions can be enhanced by boosting the spin splitting with an intrinsic exchange field provided by a ferromagnetic insulator. These findings could lead to more precise local electron thermometry or efficient microrefrigerators.

After two decades of intense investigation, the pseudogap phase of cuprate superconductors still remains a puzzle. The authors explore it by measuring the electrical resistivity and Hall coefficient of the cuprate Nd-LSCO in high magnetic fields for closely spaced doping rates across the pseudogap critical point. They report two main observations. First, both types of measurement indicate a drop of carrier density from 1+p to p upon entering the pseudogap phase; the process is best characterized as a crossover as a function of temperature at fixed doping and as a transition as a function of doping at zero temperature. Second, the mobility is unaffected by the transition. These findings, quantitively consistent with the cases of YBCO and LSCO, appear to be a universal signature of the pseudogap.
