2014 Modulation has been observed in orientation transfer from mercury to cadmium under the simultaneous application of a static and a rotating magnetic field. The dependence of the depth of modulation on the static field has been investigated, and the agreement with theory is satisfactory.

The Thomson’s Theorem states that static charge distributions in conductors show up at the conducting surfaces in an equipotential configuration, so that the electrostatic energy is a minimum. In this work we study an analogue statement for magnetic systems: in a given set of conductors, the stored magnetic field energy reaches the minimum value for superficial current distributions so that the...

We present electrical measurements of high-frequency magnetic dynamics excited by spin-polarized currents in Co/Cu/Ni(80)Fe20 nanopillar devices, with a magnetic field applied perpendicular to the sample layers. As a function of current and magnetic field, the dynamical phase diagram contains several distinguishable precessional modes and also static magnetic states. Using detailed comparisons ...

The spin reorientation of ErFeO3 that spontaneously occurs at low temperature has been previously determined to be a process involving the continuous rotation of Fe3þ spins. In this work, the dynamic process of spin reorientation in ErFeO3 single crystal has been investigated by AC susceptibility measurements at various frequencies and static magnetic fields. Interestingly, two completely disco...

Small-angle neutron scattering experiments have been performed to investigate orientational ordering of a dispersion of rod-shaped ferromagnetic nanoparticles under the influence of shear flow and static magnetic field. In this experiment, the flow and flow gradient directions are perpendicular to the direction of the applied magnetic field. The scattering intensity is isotropic in zero-shear-r...

aims: arsenic contamination of natural water resources has become an important environmental problem in the world. the adsorption method by iron filings adsorbent or zero-valent iron was used. the study aimed to evaluate the efficiency of iron filings in arsenite removal from polluted water and to investigate the effect of magnetic field on the process. materials & methods: this interventional ...

in order to compare effect of magnetic field and frigate surfactant to enhance the efficacy of iodosulfuron-methyl-sodium plus mesosulfuron-methyl (chevalier) to control wild oat, a greenhouse experiment of dose-response was conducted. treatments were 0, 3, 6, 12, 18 and 24 doses g a.i. ha-1 of chevalier (i) without treatment, (ii) with frigate % 0.1 v/v, (iii) with magnetic field, and (iv) fri...

in this study, the effects of strength and direction of the magnetic field on lid-driven cavity flow in the whole range of magnetic field strength variations, which already used in practice up to present (0 to 10 tesla), are studied. the governing equations, including conservative equations of momentum, continuity and magnetic field equations were solved numerically. momentum and continuity equ...

[1] Remote detection and measurement of the slowly varying continuing current that follows some lightning return strokes is difficult. Slow changes in quasi-static electric fields have been most frequently used to remotely measure continuing current. Because of the rapid attenuation of dipole electric fields with distance, though, the range over which the current will produce a measurable signa...

MRI is a powerful technique for clinical diagnosis and materials characterization. Images are acquired in a homogeneous static magnetic field much higher than the fields generated across the field of view by the spatially encoding field gradients. Without such a high field, the concomitant components of the field gradient dictated by Maxwell's equations lead to severe distortions that make imag...
