Stress Dependence of Hysteresis Loss on Iron-Based Soft Magnetic Materials

Rheological hysteresis in soft glassy materials.

The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress versus shear rate, which is most generally obtained by sweeping up or down the shear rate over a finite temporal window. For a huge amount of complex fluids, the up and down sweeps do not superimpose and define a rheological hysteresis loop. By means of extensive rheometry coupled to time-res...

Fabrication of Soft Magnetic Fe-based Nanoalloy

The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...

Sensors based on soft magnetic materials Panel discussion

The economic realities of productivity, quality and reliability for the industrial societies of the 21th century are placing major demands on existing manufacturing technologies. To meet both present and anticipated requirements, new and improved methods are needed. To be e!ective, the measurement, electronics and control components, and sub-systems, in particular sensors and sensor systems, ha...

Structure and Hysteresis of Patterned Soft-Magnetic Structure

Soft magnetic ternary iron-boron-based bulk metallic glasses

Ternary iron-boron-based bulk metallic glasses sBMGsd were explored exhibiting capability of thick amorphous casting at least 1 mm in rod diameter or 0.5 mm in plate thickness, excellent soft magnetic properties with saturation magnetization 1.56 T and coercivity smaller than 40 A/m, and electrical resistivity larger than 200 mV cm. The BMG alloys represented by the formulas MaFebBc are based o...
