Order-Disorder in Fe-Si Alloys: Implications for Seismic and Transport Properties of Earth's Inner Core
Cong Liu, Xin Deng, R. E. Cohen
Understanding the structure and dynamics of Earth's inner core is essential for constraining its composition, thermal evolution, and seismic behavior. Silicon is widely considered…
Stabilization of Ferroelectric Hafnia and Zirconia through Y2O3 doping
Li Yin, Cong Liu, R. E. Cohen
We investigate the possible stabilization of ferroelectricity in bulk Y2O3-doped hafnia and zirconia. We use density functional theory (DFT) with large random supercells of hafnia…
Electrical resistivity, thermal conductivity, and viscosity of Fe-H alloys at Earth's core conditions
Cong Liu, Ronald Cohen
The transport properties (electrical resistivity, thermal conductivity, and viscosity) of iron-hydrogen alloys are of great significance in the stability and evolution of planetary…
Effect of Substrate Temperature on Structural and Magnetic Properties of c-axis Ori-ented Spinel Ferrite Ni0.65Zn0.35Fe2O4 (NZFO) Thin Films
Dhiren K. Pradhan, Shalini Kumari, Dillip K. Pradhan +3
Varying the substrate temperature changes structural and magnetic properties of spinel ferrite NZFO thin films. XRD of films grown at different temperature display only 004 reflect…
