Perpendicular magnetic tunnel junctions with multi-interface free layer
Pravin Khanal, Bowei Zhou, Magda Andrade +8
Future generations of magnetic random access memory demand magnetic tunnel junctions that can provide simultaneously high magnetoresistance, strong retention, low switching energy…
On the Temperature-dependent Characteristics of Perpendicular Shape Anisotropy-Spin Transfer Torque-Magnetic Random Access Memories (PSA-STT-MRAMs)
Wei Zhang, Zihan Tong, Yuzan Xiong +2
The perpendicular shape anisotropy-spin transfer torque-magnetic random access memories (PSASTT-MRAMs) takes advantage of the nanopillar free-layer geometry for securing a good the…
Topological Hall Effect in a Topological Insulator Interfaced with a Magnetic Insulator
Peng Li, Jinjun Ding, Steven S. -L. Zhang +13
A topological insulator (TI) interfaced with a magnetic insulator (MI) may host an anomalous Hall effect (AHE), a quantum AHE, and a topological Hall effect (THE). Recent studies,…
Kondo physics in antiferromagnetic Weyl semimetal Mn3+xSn1-x films
Durga Khadka, T. R. Thapaliya, Sebastian Hurtado Parra +9
Topology and strong electron correlations are crucial ingredients in emerging quantum materials, yet their intersection in experimental systems has been relatively limited to date.…
Electrical control of metallic heavy-metal/ferromagnet interfacial states
Chong Bi, Congli Sun, Meng Xu +3
Voltage control effects provide an energy-efficient means of tailoring material properties, especially in highly integrated nanoscale devices. However, only insulating and semicond…
Spin-orbit torque switching of synthetic antiferromagnets
Chong Bi, Hamid Almasi, Kyle Price +5
We report that synthetic antiferromagnets (SAFs) can be efficiently switched by spin-orbit torques (SOTs) and the switching scheme does not obey the usual SOT switching rule. We sh…
Local sheet conductivity and sheet current density mapping using a single scanning voltage probe
Weigang Wang, Malcolm R. Beasley
We demonstrate how a single scanning voltage probe can be used to map the local conductivity and current density in a thin film with no a priori knowledge of the geometry of the el…
Measurement of specific contact resistivity using scanning voltage probes
Weigang Wang, Malcolm R. Beasley
Specific contact resistivity measurements have conventionally been heavy in both fabrication and simulation/calculation in order to account for complicated geometries and other eff…
Local transport measurements at mesoscopic length scales using scanning tunneling potentiometry
Weigang Wang, Ko Munakata, Michael Rozler +1
Under mesoscopic conditions, the transport potential on a thin film with current is theoretically expected to bear spatial variation due to quantum interference. Scanning tunneling…
Theoretical Description of Scanning Tunneling Potentiometry
Weigang Wang, Malcolm R. Beasley
A theoretical description of scanning tunneling potentoimetry (STP) measurement is presented to address the increasing need for a basis to interpret experiments on macrscopic sampl…
