Electrical resistivity, dc magnetization, ac magnetic susceptibility, and magnetic relaxation studies of polycrystalline Pr(0.2)La(0.8)Fe(11.4)Al(1.6) compound have been carried out. On the basis of the measurements of isofield magnetization and ac magnetic susceptibility, we provide evidence for phase coexistence (the appearance of the ferromagnetic phase in the antiferromagnetic matrix) rathe...

Thermally-assisted ultra-fast magnetization reversal in a DC magnetic field for magnetic multilayer thin films with perpendicular anisotropy has been investigated in the time domain using femtosecond laser heating. The experiment is set-up as an optically pumped stroboscopic Time Resolved Magneto-Optical Kerr Effect magnetometer. It is observed that a modest laser fluence of about 0.3 mJ/cm ind...

Sources on interface magnetization and anisotropy in Fe/Cu multilayers have been investigated via thermal behavior using DC magnetization and ferromagnetic resonance techniques. The samples were prepared by DC sputtering resulting in equal thickness elemental layers ranging in modulation wavelength from 1 to 30 nm. The interface anisotropy remains nearly constant at 0.32 erg/cm2 through the tem...

  YFe10V2 and NdFe10V2 interstitially modified compositions with hydrogen and nitrogen atoms were prepared by solid – gas reaction and their structural and magnetic properties were studied. The XRD patterns indicate that the samples are single phase and better than 95% and their purity improves after hydrogenation. The crystallites were broken by nitrogenation which is due to the penetration of...

The spin current pumped by a precessing ferromagnet into an adjacent normal metal has a constant polarization component parallel to the precession axis and a rotating one normal to the magnetization. The former is now routinely detected as a dc voltage induced by the inverse spin Hall effect (ISHE). Here we compute ac ISHE voltages much larger than the dc signals for various material combinatio...

An optical probe current sensor module using the Kerr effect of exchange-coupled magnetic film has been fabricated and applied to switching current measurements for IGBT used for the DC-DC converter and the DC-AC inverter of EV/HEV. Since the sensor module using the Kerr effect of the single domain exchange-coupled magnetic film utilizes magnetization rotation only, Barkhausen noise due to doma...

Induction thermography is a promising nondestructive testing technique with the advantages of high efficiency, lift-off tolerance, and defect imaging. To fulfill scanning detection quantify in bearing rings, this paper proposes eddy current under AC-DC composite magnetization. With DC magnetization, will cause permeability disturbance ring surface. Under high-frequency AC disturbed generate non...

Fast strain wave induced magnetization changes in long cobalt bars: Domain motion versus coherent rotation" (2015). A high frequency (88 MHz) traveling strain wave on a piezoelectric substrate is shown to change the magnetization direction in 40 lm wide Co bars with an aspect ratio of 10 3. The rapidly alternating strain wave rotates the magnetization away from the long axis into the short axis...
