Understanding magnetotransport signatures in networks of connected permalloy nanowires
Brian Le, Jungsik Park, Joseph Sklenar +8
The change in electrical resistance associated with the application of an external magnetic field is known as the magnetoresistance (MR). The measured MR is quite complex in the cl…
Ferromagnetism and Spin-dependent Transport in n-type Mn-Bi2Te3 Thin Films
Joon Sue Lee, Anthony Richardella, David W. Rench +5
We describe a detailed study of the structural, magnetic, and magneto-transport properties of single-crystal, n-type, Mn-doped Bi2Te3 thin films grown by molecular beam epitaxy. Wi…
Growth and Characterization of Hybrid Insulating Ferromagnet-Topological Insulator Heterostructure Devices
A. Kandala, A. Richardella, D. W. Rench +3
We report the integration of the insulating ferromagnet GdN with epitaxial films of the topological insulator Bi2Se3 and present detailed structural, magnetic and transport charact…
Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator
Duming Zhang, Anthony Richardella, David W. Rench +12
The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…
Measurement and simulation of anisotropic magnetoresistance in single GaAs/MnAs core/shell nanowires
J. Liang, J. Wang, A. Paul +6
We report four probe measurements of the low field magnetoresistance in single core/shell GaAs/MnAs nanowires synthesized by molecular beam epitaxy, demonstrating clear signatures…
Structural and Magnetic Characteristics of MnAs Nanoclusters Embedded in Be-doped GaAs
D. W. Rench, P. Schiffer, N. Samarth
We describe a systematic study of the synthesis, microstructure and magnetization of hybrid ferromagnet-semiconductor nanomaterials comprised of MnAs nanoclusters embedded in a p-d…
