A high-energy density antiferroelectric made by interfacial electrostatic engineering
Julia A. Mundy, Colin A. Heikes, Bastien F. Grosso +11
Dielectric capacitors hold a tremendous advantage for energy storage due to their fast charge/discharge times and stability in comparison to batteries and supercapacitors. A key li…
Spin scattering and noncollinear spin structure-induced intrinsic anomalous Hall effect in antiferromagnetic topological insulator
Seng Huat Lee, Yanglin Zhu, Yu Wang +8
has recently been established as an intrinsic antiferromagnetic (AFM) topological insulator and predicted to be an ideal platform to realize quantum anomalous…
Exploring interfacial exchange coupling and sublattice effect in heavy metal/ferrimagnetic insulator heterostructures using Hall measurements, x-ray magnetic circular dichroism, and neutron reflectometry
Qiming Shao, Alexander Grutter, Yawen Liu +13
We use temperature-dependent Hall measurements to identify contributions of spin Hall, magnetic proximity, and sublattice effects to the anomalous Hall signal in heavy metal/ferrim…
Magnetodielectric effects at quantum critical fields in cobalt-containing garnets
Abbey J. Neer, Veronika A. Fischer, Michelle Zheng +6
Here we present a comparative study of the magnetic and crystal chemical properties of two Co2+ containing garnets, NaCa2Co2V3O12 and CaY2Co2Ge3O12. Both phases exhibit the onset o…
Spin Seebeck imaging of spin-torque switching in antiferromagnetic Pt/NiO heterostructures
Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas +10
As electrical control of Néel order opens the door to reliable antiferromagnetic spintronic devices, understanding the microscopic mechanisms of antiferromagnetic switching is cruc…
Ionic Tuning of Cobaltites at the Nanoscale
Dustin A. Gilbert, Alexander J. Grutter, Peyton D. Murray +13
Control of materials through custom design of ionic distributions represents a powerful new approach to develop future technologies ranging from spintronic logic and memory devices…
