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 ...

Magnetic Nanoparticles Coated with a Thermosensitive Polymer with Hyperthermia Properties

Magnetic nanoparticles (MNPs) have been widely used to increase the efficacy of chemotherapeutics, largely through passive accumulation provided by the enhanced permeability and retention effect. Their incorporation into biopolymer coatings enables the preparation of magnetic field-responsive, biocompatible nanoparticles that are well dispersed in aqueous media. Here we describe a synthetic rou...

Development of Ultra-Thin Glass-Coated Amorphous Microwires for High Frequency Magnetic Sensors Applications

The giant magneto-impedance (GMI) effect has been studied in 3 different families of amorphous wires: conventional amorphous wires (125 μm in diameter), cold drawn wires (50 and 20 μm in diameter) and thin glass coated amorphous microwires (with metallic nucleus diameter of about 15 μm). These wires have been investigated in the frequency range 1 – 500 MHz. A remarkable difference in the magnet...
