Structural, Vibrational, and Magnetic Characterization of Orthoferrite LaFeO3 Ceramic Prepared by Reaction Flash Sintering
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
LaFeO3 perovskite ceramics have been prepared via reaction flash technique using Fe2O3 and La2O3 as precursors. The obtained pellets have been investigated using several techniques. The formation of LaFeO3 has been clearly ...

Effect of Thermal Treatments Below Devitrification Temperature on the Magnetic and Magnetocaloric Properties in Mechanically Alloyed Fe70Zr30 Powders
(Elsevier, 2023)
In this work, the relaxation of the amorphous structure of mechanically alloyed Fe70Zr30 powders has been analyzed through interrupted heating ramps below the devitrification temperature. As a result of such thermal ...

Study of the Kinetics and Products of the Devitrification Process of Mechanically Amorphized Fe70Zr30 Alloy
(Elsevier, 2020)
Devitrification of mechanically alloyed amorphous Fe70Zr30 at. % compound consists on a two-step process: amorphous → amorphous + bcc Fe + Fe2Zr → Fe2Zr + Fe23Zr6. This sequence is inferred from the evolution of the Mössbauer ...
