Josephson junctions containing ferromagnetic materials exhibit interesting physics and show promise as circuit elements for superconducting logic memory. For memory applications, the properties of junction should be controllable by changing magnetic configuration inside junction. To achieve good switching properties, one choose a soft material such NiFe (permalloy); however, exhibits poor super...

The magnetic characteristics of silicon steel sheet 30Q120 under different AC frequencies were measured by an Epstein frame in order to analyze the effects frequency variation on hysteresis loop ferromagnetic materials and compare differences such at frequencies. First, forecasting method properties influence using neural network was proposed based experimental data. Hysteresis loops obtained. ...

T aking advantage of the fact that electrons, photons and some elementary excitations have an intrinsic angular momentum (spin) offers a fascinating opportunity to study materials properties. Introducing a net imbalance between spins pointing in different directions (say, 'up' and 'down') is one way to probe phenomena including spin–orbit and hyperfine coupling, pairing of unconventional superc...

We demonstrate structural and room temperature magnetic properties of Fe doped ZnO nanofibers (NFs) obtained by electrospinning followed by calcination. The observed NFs, formed from crystalographically oriented, approximately 4.5 nm particles conglomerates, were approximately 200 nm in diameter. The reported synthesis of room temperature ferromagnetic Fe doped ZnO NFs is both facile and econom...

The orthogonal relation between the magnetic aspect (spin) of scatterable elementary particles’ energy with respect to their direction of motion can be demonstrated at the macroscopic level by mechanical means. It can be proven that force aligning the spins of unpaired electrons in ferromagnetic materials causes the unidirectional carrying energy of the electrons involved to align orthogonally ...

Multiferroic composite materials, consisting of coupled ferromagnetic and piezoelectric phases, are of great importance in the drive towards creating faster, smaller and more energy efficient devices for information and communications technologies. Such devices require thin ferromagnetic films with large magnetostriction and narrow microwave resonance linewidths. Both properties are often degra...

Since the prediction by Dietl et al. in the year 2000, extensive research activities have been focused on the ZnObased diluted magnetic materials (DMSs). Earlier works were mainly performed using bulk or thin film materials with transition-metal doping, and diverse magnetic properties including ferromagnetism, paramagnetism, and diamagnetism have been reported. Identifying the dominant mechanis...

Entanglement of the spin-orbit and magnetic order in multiferroic materials bears a strong potential for engineering novel electronic and spintronic devices. Here, we explore the electron and spin structure of ferroelectric α-GeTe thin films doped with ferromagnetic Mn impurities to achieve its multiferroic functionality. We use bulk-sensitive soft-X-ray angle-resolved photoemission spectroscop...

Utilization of controllable ferroelectric and ferromagnetic layers coating a conducting object to provide an attenuation capability against electromagnetic interrogation is discussed. The problem is formulated as a differential game and/or a robust optimization. The scattered field due to interrogation can be attenuated with the assumption of an uncertainty in the interrogation wave numbers. Th...
