Manipulation of Ferroic Orders via Continuous Biaxial Strain Engineering in Multiferroic Bismuth Ferrite

open access: yesAdvanced Science, EarlyView.
This study explores the evolution of ferroelectric (FE) and antiferromagnetic (AFM) orders in freestanding BiFeO3 films under anisotropic strain using rotational anisotropy second harmonic generation (RA‐SHG) and first‐principles calculations. The research reveals reversible control of in‐plane FE polarization and significant AFM order rotation ...

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

open access: yesAdvanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal
