On the order of magnetic transition in MnCo1−xFexGe (x = 0.20, 0.06 and 0.03) mechanical alloys
(Elsevier, 2023)
Mechanically amorphized MnCo1−xFexGe alloys (x = 0.20, 0.06 and 0.03) were used as precursors to obtain hexagonal austenite single phase samples. Combining thermomagnetic and magnetocaloric analysis and in situ X-ray ...

All-d-metal Ni(Co)-Mn(X)-Ti (X = Fe or Cr) Heusler Alloys: Enhanced Magnetocaloric Effect for Moderate Magnetic Fields
(Elsevier, 2023)
All-d-metal Ni(Co)-Mn-Ti Heusler alloys show high magnetocaloric/barocaloric effects ascribed to the occurrence of a martensitic transformation together with excellent mechanical properties. However, high magnetic fields ...
