Wave reversal mode in permalloy wire-tube nanostructures

چکیده
We have investigated hysteresis curves and magnetization reversal mechanisms in permalloy wire-tube nanostructures when an external magnetic field is applied perpendicular to the axis of nanostructure, x direction. Our results show that nanotube reverses its through wave mechanism, while nanowire does so pseudo-coherent rotation, according literature. The nanostructure exhibits a more complex where each segment begins revert depending on whether it wire or tube segment, but quickly entire adopts mechanism as own, considerably reducing area within curve exhibited by nanostructure. possibility alter mode such provides attractive way control motion domain walls.

Quantum transport in ferromagnetic permalloy nanostructures
We studied phase-coherent phenomena in mesoscopic permalloy Ni81Fe19 samples by exploring lowtemperature transport. Both differential conductance as a function of bias voltage and magnetoconductance of individual wires display conductance fluctuations. Analysis of these fluctuations yields a phase coherence length of 250 nm at 25 mK as well as a 1 / T temperature dependence. To suppress conduct...
متن کاملObservation of magnetization reversal of thin-film permalloy nanostructures using ballistic electron magnetic microscopy
We have imaged the magnetization reversal process of thin-film permalloy (Ni80Fe20) nanostructures using ballistic electron magnetic microscopy. Their switching behavior is often influenced by the formation of end domains and the subsequent domain-wall propagation under application of a magnetic field. Occasionally, this process leads to the formation of a 360° domain wall that is stable in fie...
متن کاملControlled magnetic reversal in Permalloy films patterned into artificial quasicrystals.
We have patterned novel Permalloy thin films with quasicrystalline Penrose P2 tilings and measured their dc magnetization and ferromagnetic resonance absorption. Reproducible anomalies in the hysteretic, low-field data signal a series of abrupt transitions between ordered magnetization textures, culminating in a smooth evolution into a saturated state. Micromagnetic simulations compare well to ...
