Uncompensated Polarization in Incommensurate Modulations of Perovskite Antiferroelectrics
Tao Ma, Zhongming Fan, Bin Xu +6
Complex polar structures of incommensurate modulations (ICMs) are revealed in chemically modified PbZrO perovskite antiferroelectrics using advanced transmission electron micro…
Order-disorder transition in the prototypical antiferroelectric PbZrO
Bin Xu, Olle Hellman, L. Bellaiche
The prototypical antiferroelectric PbZrO has several unsettled questions, such as the nature of the antiferroelectric transition, possible intermediate phase and the microscopi…
Magnetic Interactions in BiFeO: a First-Principles Study
Changsong Xu, Bin Xu, Bertrand Dupé +1
First-principles calculations, in combination with the four-state energy mapping method, are performed to extract the magnetic interaction parameters of multiferroic BiFeO. Suc…
Strain-induced effects in the electronic and spin properties of a monolayer of ferromagnetic GdAg2
Alexander Correa, Bin Xu, Matthieu J. Verstraete +1
We report on the structural, electronic and magnetic properties of a monolayer of GdAg2, forming a moiré pattern on Ag(111). Combining scanning tunneling microscopy and ab-initio s…
Non-monotonic anisotropy in charge conduction induced by antiferrodistortive transition in metallic SrTiO
Qian Tao, Bastien Loret, Bin Xu +6
Cubic SrTiO becomes tetragonal below 105 K. The antiferrodistortive (AFD) distortion leads to clockwise and counter-clockwise rotation of adjacent TiO octahedra. This i…
