Helical magnetic structure and the anomalous and topological Hall effects in epitaxial B20 FeCoGe films
Charles S. Spencer, Jacob Gayles, Nicholas A. Porter +12
Epitaxial films of the B20-structure alloy FeCoGe were grown by molecular beam epitaxy on Si (111) substrates. The magnetization varied smoothly from the bulk-like valu…
Manipulation of the spin helix in FeGe thin films and FeGe/Fe multilayers
Nicholas A. Porter, Charles S. Spencer, Rowan C. Temple +4
Magnetic materials without structural inversion symmetry can display the Dzyaloshinskii-Moriya interaction, which manifests itself as chiral magnetic ground states. These chiral st…
DMI meter: Measuring the Dzyaloshinskii-Moriya interaction inversion in Pt/Co/Ir/Pt multilayers
A. Hrabec, N. A. Porter, A. Wells +6
We describe a field-driven domain wall creep-based method for the quantification of interfacial Dzyaloshinskii-Moriya interactions (DMI) in perpendicularly magnetized thin films. T…
Scattering mechanisms in textured FeGe thin films: magnetoresistance and the anomalous Hall effect
N. A. Porter, J. C. Gartside, C. H. Marrows
A textured thin film of FeGe was grown by magnetron sputtering with a helimagnetic ordering temperature of TN = 276 +/- 2 K. From 5 K to room temperature a variety of scattering pr…
Giant topological Hall effect in strained FeCoSi epilayers
Nicholas A. Porter, Priyasmita Sinha, Michael B. Ward +7
The coupling of electron spin to real-space magnetic textures leads to a variety of interesting magnetotransport effects. The skyrmionic spin textures often found in chiral B20-lat…
Strain-induced effects on the magnetic and electronic properties of epitaxial FeCoSi thin films
P. Sinha, N. A. Porter, C. H. Marrows
We have investigated the Co-doping dependence of the structural, transport, and magnetic properties of ε-FeCoSi epilayers grown by molecular beam epitaxy on silicon (111) substrate…
Linear magnetoresistance in commercial n-type silicon due to inhomogeneous doping
Nicholas Porter, Christopher Marrows
Free electron theory tells us that resistivity is independent of magnetic field. In fact, most observations match the semiclassical prediction of a magnetoresistance that is quadra…
