Mapping universal conductance fluctuations
J. Berezovsky, M. F. Borunda, E. J. Heller +1
Graphene provides a fascinating testbed for new physics and exciting opportunities for future applications based on quantum phenomena. To understand the coherent flow of electrons…
Spatial Imaging of Magnetically Patterned Nuclear Spins in GaAs
J. Stephens, R. K. Kawakami, J. Berezovsky +4
We exploit ferromagnetic imprinting to create complex laterally defined regions of nuclear spin polarization in lithographically patterned MnAs/GaAs epilayers grown by molecular be…
Imaging of Spin Dynamics in Closure Domain and Vortex Structures
J. P. Park, P. Eames, D. M. Engebretson +2
Time-resolved Kerr microscopy is used to study the excitations of individual micron- scale ferromagnetic thin film elements in their remnant state. Thin (18 nm) square elements wit…
Spatially Resolved Dynamics of Localized Spin-Wave Modes in Ferromagnetic Wires
J. P. Park, P. Eames, D. M. Engebretson +2
We have observed localized spin-wave modes in individual thin-film ferromagnetic wires using time-resolved Kerr microscopy as a micron-scale spectroscopic probe. The localization i…
Time-resolved ferromagnetic resonance in epitaxial Fe1-xCox films
D. M. Engebretson, S. Zellinger, L. C. Chen +2
Magnetodynamics in epitaxial Fe1-xCox films on GaAs (100) are studied using time-resolved ferromagnetic resonance, in which the free precession of the magnetization after an impuls…
