First-principles study on the magnetic properties in Mg dooped BiFeO3 with and without oxygen vacancies
Vacancies Magnesium Magnetic moments Antiferromagnetism Band gap
2016/12/2
The magnetic properties of Mg-doped BiFeO3 (BFO) with and without oxygen vacancies are studied through first-principles calculations. The Mg-doping prefers to occupy the ferromagnetic planes and produ...
Atmospheric Oxygen Binding and Hole Doping in Deformed Graphene on a SiO2 Substrate
graphene Raman spectroscopy scanning tunneling microscopy (STM)
2010/11/22
Using micro-Raman spectroscopy and scanning tunneling microscopy, we study the relationship between structural distortion and electrical hole doping of graphene on a silicon dioxide substrate. The obs...
Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)
cuprate superconductors Oxygen nuclear-magnetic-resonance investigation
2010/11/18
The critical doping levels in cuprates, where the ground state changes its nature (from an an-
tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
Oxygen Ion Implantation in Strontium Bismuth Tantalate Thin Films
Ferroelectric Thin films SBT Oxygen implantation Plasma focus
2010/9/29
Strontium Bismuth Tantalate (SBT) ferroelectric thin films have attracted considerable attention for the development of non-volatile ferroelectric random access memories (NV-FRAMs). These films, howev...
