Effect of Pressure on the Phase Stability and Magnetostructural Transitions in Nickel-rich NiFeGa Ribbons
(Elsevier, 2020)
Ribbons of a Ni55Fe19Ga26 Heusler alloy were prepared by melt spinning technique. The effect of pressure on magnetostructural transitions was studied comparing as-spun ribbons to ribbons previously submitted to an axial ...

Crystallization kinetics and soft magnetic properties in metalloid-free (Fe, Co)90Zr10 amorphous and nanocrystalline alloys
(Elsevier, 2014)
Microstructure and magnetic properties of metalloid-free (Fe100- xCox)90Zr10 amorphous and nanocrystalline alloys were characterized. Devitrification of these amorphous alloys occurs in two overlapped transformations leading ...

Milling effects on the distribution of Curie temperatures and magnetic properties of Ni-doped La0·7Ca0·3MnO3 compounds
(Elsevier, 2020)
A systematic study of the magnetic and magnetocaloric properties around the ferromagnetic-paramagnetic phase transition temperature have been carried out on La0.7Ca0.3Mn1-xNixO3 (x = 0, 0.02, 0.07, 0.10) compounds ...

Ultraslow calorimetric studies of the martensitic transformation of NiFeGa alloys: detection and analysis of avalanche phenomena
(Springer Nature, 2024-05)
We study the thermal properties of a bulk Ni55 Fe19 Ga26 Heusler alloy in a conduction calorimeter. At slow heating and cooling rates (∼ 1 K/h ), we compare as-cast and annealed samples. We report a smaller thermal hysteresis ...
