“…The PC membrane is soaked in the aqueous electrolytic solution composed of NiSO 4 and H 3 BO 4 at pH = 6.2. During the electrochemical action, Ni nanowires is growing up in the cylindrical pores of the membrane, when one of them is filled, the current through the two electrodes (gold layers) is soaring from zero to high intensity and then we can terminate the sample production process [8,18,19].…”

In this work, we study the magnetic properties of nickel nanowires by measuring their anisotropic magnetoresistance at room temperature. The single nickel nanowire is grown by electrodeposition in a polymer membrane (Polycarbonate). We measure the anisotropic magnetoresistance effect of nickel nanowires for the various values of the magnitudes and orientations of an external magnetic field. The results clearly show the existence the anisotropic magnetoresistance effect in the nickel nanowires. Besides, the experimental data are best fit to the analytical calculations using the Stoner-Wohlfarth model for the magnetization of the wires.

The difficulty to generate and control large strain gradients in materials hinders the investigation and application of flexoelectricity and flexomagnetism. This work demonstrates that thermal expansion can be used to induce very large non‐uniform strains at the nanoscale, resulting in giant strain gradients at moderate temperatures. This is demonstrated in a nanopatterned multiferroic hybrid layer consisting of a regular array of ferromagnetic metallic nanocylinders embedded in a ferroelectric polymer matrix. The thermally‐induced strain gradients can fully depolarize the ferroelectric component, and modify the magnetization of the ferromagnetic component via flexoelectric and flexomagnetic effects, respectively. Finite‐element analysis provides a quantitative view on thermal expansion‐induced strains and strain gradients supporting the experimental findings. This work shows that nanoscale thermal strain engineering provides an additional degree of freedom to control electrical polarization and magnetization, which paves the way for the design and operation of novel functional devices and nanostructures.

Investigation of the thermoelastic‐tunable magnetic response of polycrystalline bismuth ferrite thin film is herein reported. The polycrystalline bismuth ferrite thin films were grown by room‐temperature pulsed laser deposition on the designed polymer colloidal photonic crystal substrates. The evolution of these films was assessed by X‐ray diffraction testing and scanning electron microscopy images. The thermal‐dependent magnetic measurements and magneto‐optical properties were also investigated as a function of deposition substrate and target–substrate distances via the Faraday rotation method. Due to the large anisotropic thermal deformation of the polymer colloidal interface, the huge rotation downshift was observed versus a slight thermal change. Furthermore, we found that this returnable reduction had the same behavior during the heating and cooling processes. This reversible thermal property of the polymer colloidal crystal in combination with the magnetic response of the multiferroic compounds can possibly lead to innovations in sensors and switches based on thermomagneto‐optical coupling and facilitate the nanoscale thermal characterization.
