Cation exchange chemistry as a route to induce noncentrosymmetry in layered perovskite oxides

, 2022
This work is focused on the synthesis and characterisation of n = 2 Layered Perovskite Oxides. KNdM2O7 (M = Ta, Nb) were synthesized by a two-step cation exchange reaction from RbNdM2O7 via NaNdM2O7. The K-phases adopt a polar Im2m structure.

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling
