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 ...
