Temperature dependent magnetic and structural properties of Al substituted nanostructured hexaferrites with large coercive fields

Pierfrancesco Maltoni, Ravi Kiran Dokala, Prativa Pramanik, Rafael Araujo et autres

We report a comprehensive study of the temperature-dependent structural, magnetic, vibrational, and dielectric properties of Al-substituted M-type hexaferrites SrFe 12-x Al x O 19 . Neutron powder diffraction and Mössbauer spectrometry show that Al 3+ preferentially replaces Fe 3+ at spin-up octahedral …

Facile and fast synthesis of highly ordered L10-FeNi nanoparticles

Gaspare Varvaro, Patrizia Imperatori, S. Laureti, Davide Peddis et autres

The chemically ordered L10-FeNi alloy is a promising candidate for next generation rare-earth-free permanent magnets, which can revolutionize the high-performance magnets market currently dominated by Nd-Fe-B. Despite many efforts, the experimental results fall short of theoretical predictions, and current approaches are not …
