Atomic-Scale Observation of Symmetry Breaking in Altermagnetic MnTe
Guodong Ren, Jonathan M. DeStefano, Xiao-Wei Zhang +20
The recent discovery of altermagnetism has sparked growing interest in compensated magnetic systems as promising platforms for highly scalable spintronics. Altermagnetism is a dist…
Improper flexoelectricity in hexagonal rare-earth ferrites
Xin Li, Guodong Ren, Yu Yun +5
Flexoelectricity is a universal effect that generates electric polarization due to broken inversion symmetry caused by local strain gradient. The large strain gradient at nanoscale…
Strong tunability of epitaxial relationship and reconstruction at improper ferroelectric interface
Xin Li, Yu Yun, Guodong Ren +4
The atomic structures at epitaxial film-substrate interfaces determine scalability of thin films and can result in new phenomena. However, it is challenging to control the interfac…
Polarization Pinning at Antiphase Boundaries in Multiferroic YbFeO
Guodong Ren, Pravan Omprakash, Xin Li +4
The switching characteristics of ferroelectrics and multiferroics are influenced by the interaction of topological defects with domain-walls. We report on the pinning of polarizati…
