An Electrode Design Strategy to Minimize Ferroelectric Imprint Effect

Advanced Science, EarlyView.
A tunable electrode design using La0.7Sr0.3MnO3 enables precise modulation of ferroelectric imprint through oxygen pressure–controlled work function engineering. By applying this strategy to both perovskite and fluorite systems, the built‐in field is effectively suppressed, enabling low‐voltage, high‐endurance ferroelectric devices, including Fe‐FETs ...

Carrier-mediated magnetoelectricity in complex oxide heterostructures

, 2007
While tremendous success has been achieved to date in creating both single phase and composite magnetoelectric materials, the quintessential electric-field control of magnetism remains elusive. In this work, we demonstrate a linear magnetoelectric effect

Magnetoelectric Coupling on the Fused Azulene Oligomers

, 2021
The global magnetic phase diagram for fused azulene oligomers is obtained by using a fermionic Hubbard Hamiltonian, a intermediate model between the molecular (Pariser-Parr-Pople empiric Hamiltonian) and spin-1/2 antiferromagnetic Heisenberg approaches.

Microscopic Origin of Magnetoelectric Coupling in Noncollinear Multiferroics

Physical Review Letters, 2008
An universal microscopic mechanism to understand the interplay between the electric and magnetic degrees of freedom in noncollinear multiferroics is developed. In a system with a strong spin-orbit coupling, we show that there is a pure electric mechanism that the ferroelectricity is generated by noncollinear magnetism through an electric current ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, EarlyView.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...
