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 ...

Enhancement of the Magnetic Refrigerant Capacity in Partially Amorphous Fe 70Zr 30 Powders Obtained by Mechanical Alloying
(Elsevier, 2012)
After mechanical alloying Fe 70Zr 30 composition from pure starting powders, an amorphous phase with Curie temperature T C = 244 K and an intermetallic compound (that should be non-stoichiometric Zr-rich fcc Fe 2Zr phase) ...

Structure and magnetic properties of Fe–Nb–B amorphous/nanocrystalline alloys produced by compaction of mechanically alloyed powders
(AIP Publishing, 2010)
Mechanical alloying of Fe75Nb10B15 and Fe85Nb5B10 systems has been performed from an initial mixture of elemental powders. A bcc supersaturated solid solution is developed during milling for both alloys. However, Fe75Nb10B15 ...

Reactive flash sintering of SrFe12O19 ceramic permanent magnets
(Elsevier, 2022)
Reactive flash-sintering technique has been used in order to obtain strontium ferrite magnets from a mixture of SrCO3 and Fe2O3 commercial powders. This technique allows preparing sintered SrFe12O19 at a furnace temperature ...

Detection of the onset of nanocrystallization by calorimetric and magnetic measurements
(AIP Publishing, 2005-01-24)
It is generally accepted that measurements of the magnetic properties are more sensitive than measurements of the enthalpy changes in the detection of the onset of crystallization of ferromagnetic phases emerging from a ...

Thermal and Microstructural Stability of the Soft Magnetic Fe60Co18Nb6B15Cu1 alloy
(Elsevier, 2007)
Temperature evolution of the coercivity of nanocrystalline samples of Fe60Co18Nb6B15Cu1 alloy with different crystalline fractions was measured from room temperature up to 690 K. Although room temperature coercivity increases ...

Study of Phases Evolution in High-coercive MnAl Powders Obtained Through Short Milling Time of Gas-atomized Particles
(Elsevier, 2017)
Gas-atomized Mn54Al46 particles constituted nominally of only ε- and γ2-phases, i.e. no content of the ferromagnetic L10-type τ-phase, have been used to study the evolution of phases during short time of high-energy milling ...
