Obtaining magnetocaloric MnCo(Fe)Ge intermetallics from low temperature treatment of mechanically alloyed precursors
(Elsevier, 2020)
Production of the intermetallic MnCo0.8Fe0.2Ge phase, interesting as magnetocaloric material, is obtained by using an almost fully amorphous mechanically alloyed precursor. Thermal treatment to develop the intermetallic ...

An insight on the design of mercapto functionalized swelling brittle micas
(Academic Press Inc., 2020-03-01)
Surface modification of natural clay minerals with reagents containing metal chelating groups has great environmental value. The functionalization by adsorption or grafting guarantees a durable immobilization of the reactive ...

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 ...

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 ...

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 ...
