Angular dependence of the giant magneto impedance (GMI), hysteresis loops and magnetization curves have been investigated in amorphous wires with respect to direction amplitude magnetic field room temperature. The measurements were performed at different orientation angles applied relative wire axis various strengths moderate (0–200 Oe) high (0–5000 ranges. highest GMI response (500%) (100 emu/gr) found for close range. By increasing angle from 0°, external fields decrease without reaching...

In this paper, doped bismuth ferrite nanoparticles with barium (Bi[Formula: see text]Ba[Formula: text]FeO[Formula: text], [Formula: text] = 0.1, 0.15, 0.2) were synthesized by co-precipitation method in the presence of various surface activators. Structural properties, magnetic properties and size investigated different techniques such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning microscope (SEM), dynamic light...

In this work, Bi1−x Ba x FeO3 nanoparticles were synthesized by a hydrothermal method in the presence of various surface activators, and different amounts barium inserted bismuth ferrite (x = 0.1, 0.15, 0.2) structure instead bismuth. The structural magnetic properties, morphology, size investigated XRD, FT-IR, FE-SEM, TEM, DLS VSM. XRD analysis results reveal that synthetic have single phase. A phase shift from rhombohedral to tetragonal occurs due enhanced amount structure. SEM exhibits...

Nanostructured CoFe thin films were prepared on the glass substrates by spray pyrolysis deposition (SPD) method. The as-deposited separately annealed at 500°C in ambient air and hydrogen atmospheres to investigate effect of annealing atmosphere different properties deposited films. Structural, morphological, magnetic electrical investigated X-ray diffractometer (XRD), scanning electron microscope (SEM), vibrating sample magnetometer (VSM) four-point probe measurements, respectively. XRD...

Cobalt-based amorphous alloys, in particular CoFeBSi, have been widely used to study the response of ac-impedance external dc magnetic field, i.e., so-called Giant Magneto Impedance (GMI) effect. The utility CoFeBSi different applications such as field-sensitive sensors is known and practiced. Despite wealth experimental studies on GMI properties no computational approach has yet addressed electronic these systems at nanoscales. In this study, we computed alloys using a combined Molecular...

To investigate the behavior of tracked mobile robots or vehicles, first a mathematical model is developed to describe physics vehicles. Then, equations motion are solved for radius rotation in steady state condition using numerical method. Results compared with an ideal differentially-driven vehicle and notable similarities observed. Further, few functions approximate turning characteristics on rigid ground. Forms these simple can be used real time control planning Finally, results similar...
