The Villari effect in Fe–Cr–B amorphous ribbons

The influence of the magnetic field on the elastic properties of anisotropic magnetorheological elastomers

“…The magnetic behavoiur of the samples was examined in 50 Hz ac fields, by means of an integrating fluxmeter [18]; in Fig. 1 the hysteresis loop of the sample S 4 is shown (similar loops resulted for the lower particles density samples S 1 , S 2 and S 3 ).…”

Study on the formation of CoxFe3−xO4 system using two low temperature synthesis methods

“…The magnetic curves show a high coercive field due to the high magnetic anisotropy of cobalt ferrite [21].…”

“…The annealing products were characterized by XRD with a diffractometer D8 Advanced-Bruker AXS, using Mo-K a (l Mo = 0.7093 Å ) radiation and by FT-IR. Magnetic properties of the obtained powders have been studied using a conventional induction method [21], in AC magnetic fields up to 150 kA m À1 .…”

Influence of polyols on the formation of nanocrystalline nickel ferrite inside silica matrices

“…The magnetic investigation of the nanocomposites in the asprepared state was carried out at room temperature under AC (50 Hz) applied magnetic fields of amplitudes up to 5 kOe by means of an integrating fluxmeter-type hysteresigraph described elsewhere [20]. The saturation magnetization (technical) was estimated by extrapolation to 50 kOe, using a superposition of Langevin-type fitting functions.…”
