Dynamical Negative Differential Resistance in Antiferromagnetically Coupled Few-Atom Spin-Chains
Steffen Rolf-Pissarczyk, Shichao Yan, Luigi Malavolti +3
We present the appearance of negative differential resistance (NDR) in spin-dependent electron transport through a few-atom spin-chain. A chain of three antiferromagnetically coupl…
All-Electronic Nanosecond-Resolved Scanning Tunneling Microscopy: Facilitating the Investigation of Single Dopant Charge Dynamics
Mohammad Rashidi, Wyatt Vine, Jacob A. J. Burgess +5
The miniaturization of semiconductor devices to the scales where small numbers of dopants can control device properties requires the development of new techniques capable of charac…
Closing the superconducting gap in small Pb-nanoislands with high magnetic fields
Steffen Rolf-Pissarczyk, Jacob A. J. Burgess, Shichao Yan +1
Superconducting properties change in confined geometries. Here we study the effects of strong confinement in nanosized Pb-islands on Si(111) 7x7. Small hexagonal islands with diame…
Non-locally sensing the magnetic states of nanoscale antiferromagnets with an atomic spin sensor
Shichao Yan, Luigi Malavolti, Jacob A. J. Burgess +3
The ability to sense the magnetic state of individual magnetic nano-objects is a key capability for powerful applications ranging from readout of ultra-dense magnetic memory to the…
Entanglement-induced Kondo screening in atomic spin chains
Deung-Jang Choi, Roberto Robles, Shichao Yan +6
Quantum entanglement permeates the complex ground states of correlated electron materials defying single-particle descriptions. Coupled magnetic atoms have potential as model syste…
Nanoscale Structure, Dynamics, and Aging Behavior of Metallic Glass Thin Films
Jacob A. J. Burgess, Chris M. B. Holt, Erik J. Luber +6
Scanning tunneling microscopy (STM) observations resolve the structure and dynamics of metallic glass CuHf films and demonstrate STM control of aging at a metallic…
Nanomechanical AC Susceptometry of an Individual Mesoscopic Ferrimagnet
Joseph E. Losby, Zhu Diao, Fatemeh Fani Sani +5
A novel method for simultaneous detection of both DC and time-dependent magnetic signatures in individual mesoscopic structures has emerged from early studies in spin mechanics. Mu…
A Deformable Model for Magnetic Vortex Pinning
Jacob A. J. Burgess, Joseph E. Losby, Mark R. Freeman
A two-parameter analytical model of the magnetic vortex in a thin disk of soft magnetic material is constructed. The model is capable of describing the change in evolution of net v…
Thermo-mechanical sensitivity calibration of nanotorsional magnetometers
Joseph Losby, Jacob A. J. Burgess, Zhu Diao +3
We report on the fabrication of sensitive nanotorsional resonators, which can be utilized as magnetometers for investigating the magnetization dynamics in small magnetic elements.…
Observation of Magnetic Supercooling of the Transition to the Vortex State
J. P. Davis, D. Vick, J. A. J. Burgess +5
We demonstrate that the transition from the high-field state to the vortex state in a nanomagnetic disk shows the magnetic equivalent of supercooling. This is evidence that this ma…
Nano-Torsional Resonator Torque Magnetometry
J. P. Davis, D. Vick, D. C. Fortin +3
Magnetic torque is used to actuate nano-torsional resonators, which are fabricated by focused-ion-beam milling of permalloy coated silicon nitride membranes. Optical interferometry…
