Abstract Being a facet of flexible electronics, mechanically reshapeable magnetic field sensorics enable novel device ideas for soft robotics, interactive devices virtual- and augmented reality point care diagnostics. These applications demand compliant yet robust sensor revealing high sensitivity to small fields. To push the detection limit highly linear sensors be in sub-µT range, we explore new fundamental concept sensing, namely planar Hall effect thin films. With their remarkable...
The hysteretic conduction characteristics and fatigue profile of La1/3Ca2/3MnO3 (LCMO)-based memristive devices were investigated. oxide films grown by pulsed laser deposition (PLD) sandwiched between Ag Pt electrodes. exhibit bipolar resistive switching (RS) effect with well-defined intermediate states that arise from partial SET RESET events. current-voltage curves are modeled simulated using a compact approach. Two equations considered: one for the electron transport based on double-diode...
Understanding the effect of fabrication conditions on domain wall motion in thin films with perpendicular magnetization is a mandatory issue order to tune their properties aiming design spintronics devices based such phenomenon. In this context, present work intends show how different growth may affect prototypical system Pt/Co/Pt. The trilayers were deposited by dc sputtering, and parameters varied study Co thickness, substrate roughness, base pressure deposition chamber. Magneto-optical...

Optimal conditions generate appropriate monolayer...
Magnetofluidics is a dynamic research field, which requires novel sensor solutions to boost the detection limit of tiny quantities magnetized objects. Here, we present sensing strategy relying on planar Hall effect sensors in droplet-based micro-magnetofluidics for multiphase liquid flow, i.e., superparamagnetic aqueous droplets an oil carrier phase. The high resolution allows nanoliter-sized with concentration 0.58 mg/cm3, even when they are biased geomagnetic field only. can be boosted...
Influence of random point defects introduced by proton irradiation on the flux creep rates and magnetic field dependence critical current density Jc co-evaporated GdBa2Cu3O7 coated conductors

The objective of this study was to demonstrate the possibility using 1-butanol reliably detect open-pore current pyramidal solid-state nanopores produced in silicon wafers. were through controlled pore formation by neutralizing an etchant (KOH) with a strong acid (HCl). Since method are deeper than those made nanometer-thick membranes, they behave as nanochannels. As consequence, detection is more challenging. Thus, we report that low amounts butanol considerably aid nanopores.
