Nanoscale magnetic field sensing with spin-Hall nano-oscillator devices

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Yanyou Xie, Hil Fung Harry Cheung, Gregory D. Fuchs, , | Summary: In this work, we develop a nanoscale magnetic field sensor based on a spin-Hall nano-oscillator (SHNO) device. We fabricate constriction-based SHNO devices using Ni$_{81}$Fe$_{19}$/Au$_{0.25}$Pt$_{0.75}$ bilayer and use them to demonstrate quasi-DC sensing up to […]

Limits to the strain engineering of layered square-planar nickelate thin films

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Dan Ferenc Segedin, Berit H. Goodge, Grace A. Pan, Qi Song, Harrison LaBollita | Summary: The layered square-planar nickelates, Nd$_{n+1}$Ni$_{n}$O$_{2n+2}$, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd$_{6}$Ni$_{5}$O$_{12}$ thin films. Here, we investigate […]
