Tuning the perpendicular anisotropy of ferromagnetic films by thickness, width, and profile
Gregory Kopnov, Alexander Gerber
Perpendicular magnetic anisotropy was found to be highly sensitive to the nominal thickness and morphology of laterally heterogeneous CoPd films in the vicinity of the metal insula…
Resistivity testing of palladium dilution limits in CoPd alloys for hydrogen storage
S. S. Das, G. Kopnov, A. Gerber
Palladium satisfies most of the requirements for an effective hydrogen storage material with two major drawbacks: it has a relatively low gravimetric hydrogen density and is prohib…
Non-reciprocal magnetoresistance, directional inhomogeneity and mixed symmetry Hall devices
Gregory Kopnov, Alexander Gerber
Phenomenology similar to the nonreciprocal charge transport violating Onsagers reciprocity relations can develop in directionally inhomogeneous conducting films with nonuniform Hal…
Kinetics of the lattice response to hydrogen absorption in thin Pd and CoPd films
S. S. Das, G. Kopnov, A. Gerber
Hydrogen can penetrate reversibly a number of metals, occupy the interstitial sites and cause large expansion of the crystal lattice. The question discussed here is whether the kin…
Positive versus negative resistance response to hydrogenation in palladium and its alloys
Sudhansu Sekhar Das, Gregory Kopnov, Alexander Gerber
Resistive solid state sensors are widely used in multiple applications, including molecular and gas detection. Absorption or intercalation of the target species varies the lattice…
Detection of hydrogen by the extraordinary Hall effect in CoPd alloys
S. S. Das, G. Kopnov, A. Gerber
Effect of hydrogen adsorption on the extraordinary Hall phenomenon (EHE) in ferromagnetic CoPd films is studied as a function of composition, thickness, substrate and hydrogen conc…
