Spinel MgAl2O4 and family oxides are emerging barrier materials useful for magnetic tunnel junctions (MTJs). We report large magnetoresistance (TMR) ratios up to 429% at room temperature (RT) 1,034% 10 K in a Fe/MgAl2O4/Fe(001)-based MTJ prepared using electron-beam evaporation of Mg4Al-Ox. Resistance oscillations with thickness 0.3-nm were significantly enhanced compared those Fe/MgO/Fe(001) M...

Sintering is a key step in the processing of high performance ceramics. Both density and grain size play crucial role on ceramic sintering kinetics final material properties. The master curve (MSC) well-known tool for exploring models kinetics. However, conventional MSC theory assumes unique trajectory, while our study MgAl2O4 spinel shows dissimilar growth response. Park's has been applied com...

Mo-Si-B intermetallics consisting of the phases Mo3Si and Mo5SiB2, and a molybdenum solid solution (“ -Mo”), have melting points on the order of 2000 °C. These alloys have potential as oxidationresistant ultra-high-temperature structural materials. They can be designed with microstructures containing either individual -Mo particles or a continuous -Mo phase. A compilation of existing data shows...
