Direct observation of the ice rule in artificial kagome spin ice
Yi Qi, T. Brintlinger, John Cumings
Recently, significant interest has emerged in fabricated systems that mimic the behavior of geometrically-frustrated materials. We present the full realization of such an artificia…
Kondo Physics in Nanotubes: Magnetic-field dependence and singlet-triplet Kondo
C. H. L. Quay, John Cumings, Sara Gamble +3
In a single-walled carbon nanotube, we observe the spin-1/2 Kondo effect. The energy of spin-resolved Kondo peaks is proportional to magnetic field at high fields, contrary to rece…
Transport Properties of Carbon Nanotube C Peapods
C. H. L. Quay, John Cumings, S. J. Gamble +4
We measure the conductance of carbon nanotube peapods from room temperature down to 250mK. Our devices show both metallic and semiconducting behavior at room temperature. At the lo…
A Tunable Anomalous Hall Effect in a Non-Ferromagnetic System
J. Cumings, L. S. Moore, H. T. Chou +4
We measure the low-field Hall resistivity of a magnetically-doped two-dimensional electron gas as a function of temperature and electrically-gated carrier density. Comparing these…
