Suppression of Curie temperature through severe shear strain in lanthanum manganite LaMnO3+ <i>δ</i>
The effects of severe shear stress on the electron-transfer-induced ferromagnetism of lanthanum manganite LaMnO3+δ have been investigated. Shear stress was applied via high-pressure torsion (HPT) proc...
Morphological confinement of secondary phases in entropy stabilized oxides
Four transition metal entropy-stabilized oxide samples were synthesized with varying processing methods to create four different average grain sizes: 90 nm, 200 nm, 430 nm, and 15 μm. All samples were...
Achieving ultra-low surface roughness on aluminum alloys via picosecond laser milling–polishing
Producing high-quality milled surfaces on metals, particularly aluminum alloys, using laser-based techniques remains a considerable processing challenge, especially when ultra-low surface roughness is...
