Tuning the exchange bias on a single atom from 1 mT to 10 T
Kai Yang, William Paul, Fabian D. Natterer +8
Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays im…
Engineering the eigenstates of coupled spin-1/2 atoms on a surface
Kai Yang, Yujeong Bae, William Paul +8
Quantum spin networks having engineered geometries and interactions are eagerly pursued for quantum simulation and access to emergent quantum phenomena such as spin liquids. Spin-1…
Reading and Writing Single-Atom Magnets
Fabian D. Natterer, Kai Yang, William Paul +5
The highest-density magnetic storage media will code data in single-atom bits. To date, the smallest individually addressable bistable magnetic bits on surfaces consist of 5-12 ato…
Interplay between Orbital Magnetic Moment and Crystal Field Symmetry: Fe atoms on MgO
S. Baumann, F. Donati, S. Stepanow +15
We combine density functional theory, x-ray magnetic circular dichroism, multiplet calculations, and scanning tunneling spectroscopy to assess the magnetic properties of Fe atoms a…
Transient adhesion and conductance phenomena in initial nanoscale mechanical contacts between dissimilar metals
William Paul, David Oliver, Yoichi Miyahara +1
We report on transient adhesion and conductance phenomena associated with tip wetting in mechanical contacts produced by the indentation of a clean W(111) tip into a Au(111) surfac…
FIM tips in SPM: Apex orientation and temperature considerations on atom transfer and diffusion
William Paul, David Oliver, Yoichi Miyahara +1
Atoms transferred to W(111) and W(110) tip apices from the Au(111) surface during tunneling and approach to mechanical contact experiments in STM are characterized in FIM at room t…
