Synthesis and structural, magnetic and magnetotransport properties of permalloy powders containing nanoparticles prepared by arc discharge.

Highlights: [•] New method of arc discharge used to synthesise permalloy containing nanoparticles. [•] The highest quality powders were made using a 78% Ni permalloy rod in N2. [•] The Saturation moment was slightly less and the coercive field was low (3mT). [•] MR contributions from the spin-dependent tunneling between the particles. [Copyright &y& Elsevier]
