Multiferroic VHfO with Strain-Tunable Magnetism
Qisheng Yu, Tianyuan Zhu, Boyu Liu +2
The coexistence of ferroelectricity and magnetism in a single-phase oxide is rare because the electronic requirements for these two orders are often incompatible. Here, using first…

Origin of Anomalous Size Effects in Ferroelectric Hafnia Thin Films
Tianyuan Zhu, Jingxuan Li, Zuhuang Chen +1
The persistence of ferroelectricity in ultrathin HfO films challenges conventional theories, particularly given the paradoxical observation that the out-of-plane lattice spacin…

Unexpected Density Functional Dependence of the Antipolar Phase in HfO
Di Fan, Tianyuan Zhu, Shi Liu
The antipolar phase of HfO has been suggested to play an important role in the phase transition and polarization switching mechanisms in ferroelectric hafnia. In this st…
