Magnetic Nanoparticles of (Co_0.94Fe_0.06)_72.5Si_12.5B₁₅ and Fe₇₈Si₉B₁₃ Obtained by Electric Explosion of Amorphous Wires

Abstract

(EEW) is one of the promising physical methods for the MNP production [2]. Usually wires with polycrystalline structure are used for the production of nanopowders. It's known that the structure parameters of a wire affect the particles size. Thus according to the results obtained in [3] the reduction of the grain size of the wire leads to the reduction of particle sizes. In this connection the explosion of a wire without crystal structure is of interest. In this work we present the results of the synthesis of magnetic nanoparticles (MNPs) by EEW from the amorphous wires made of Co and Fe alloys with Si and B additives. The structure, morphological features and magnetic properties were studied by different techniques.
