Nanoscale electrical conductivity imaging using a nitrogen-vacancy center in diamond
Amila Ariyaratne, Dolev Bluvstein, Bryan A. Myers +1
The electrical conductivity of a material can feature subtle, nontrivial, and spatially-varying signatures with critical insight into the material's underlying physics. Here we dem…

Double-quantum spin-relaxation limits to coherence of near-surface nitrogen-vacancy centers
Bryan A. Myers, Amila Ariyaratne, Ania C. Bleszynski Jayich
We probe the relaxation dynamics of the full three-level spin system of near-surface nitrogen-vacancy (NV) centers in diamond to define a relaxation time that helps resolve…

Magnetic properties of Cobalt films described by second order perturbed Heisenberg Hamiltonian
P. Samarasekara, Amila D. Ariyaratne
Second order perturbed Heisenberg Hamiltonian was employed to investigate the magnetic properties of hexagonal Cobalt films. Initially the number of nearest neighbors and the const…
