Tailoring GMI effect in Co-rich glass coated microwires by Joule heating

GMI Effect of Ultra-Soft Magnetic Soft Amorphous Microwires

In this paper we experimentally studied GMI effect and soft magnetic behavior of Co-rich microwires. Correlation between magnetoelastic anisotropy and magnetic field dependences of diagonal and off-diagonal impedance components are observed. Low field GMI hysteresis, explained in terms of magnetoelastic anisotropy of microwires, has been suppressed by the bias current.

Ferromagnetic glass-coated microwires with good heating properties for magnetic hyperthermia

The heating properties of Fe71.7Si11B13.4Nb3Ni0.9 amorphous glass-coated microwires are explored for prospective applications in magnetic hyperthermia. We show that a single 5 mm long wire is able to produce a sufficient amount of heat, with the specific loss power (SLP) reaching a value as high as 521 W/g for an AC field of 700 Oe and a frequency of 310 kHz. The large SLP is attributed to the ...

Magnetization Reversal in System of Two Co-rich Amorphous Microwires

The present work reports on the investigations of the magnetization reversal of the system of two glass covered amorphous microwires with circular magnetic bistability. The experiments have been carried out using the transverse magneto-optical Kerr effect in circular and axial magnetic field. The electric current flowing through two wires in opposite directions produced the circular magnetic fi...

Remote Joule heating by a carbon nanotube.

Minimizing Joule heating remains an important goal in the design of electronic devices. The prevailing model of Joule heating relies on a simple semiclassical picture in which electrons collide with the atoms of a conductor, generating heat locally and only in regions of non-zero current density, and this model has been supported by most experiments. Recently, however, it has been predicted tha...
