The morphology of the dark and bright regions observed by transmission electron microscopy for the Zr(64.13)Cu(15.75)Ni(10.12)Al(10) bulk metallic glass strongly depends on the ion beam parameters used for ion milling. This indicates that the ion beam could introduce surface fluctuation to metallic ...

The effects of B and C substitution for Sn on phase components, Curie temperature T-C, and magnetocaloric effect of melt-spun Mn3Sn2-xMx (M = B, C; x = 0-0.5) ribbons have been investigated. X-ray diffraction (XRD) results show that the main phase in the as-spun Mn3Sn2-xMx (M = B, C; x = 0-0.5) ribb...

We report the magnetotransport properties of the heterojunction composed of La0.82Ca0.18MnO3 (LCMO) and 0.5 wt % Nb-doped SrTiO3 (SNTO). At temperature below 120 K, the heterojunction only exhibits a negative magnetoresistance (MR) independent of bias current. At temperatures above 120 K, with incre...

The microstructure of a low-carbon steel after high current density electropulsing treatment was characterized by high-resolution transmission electron microscopy. It was found that nanostructured gamma-Fe could be formed in the coarse-grained steel after the electropulsing treatment. The mechanism ...
