Conduction of topologically-protected charged ferroelectric domain walls

, 2011
We report on the observation of nanoscale conduction at ferroelectric domain walls in hexagonal HoMnO3 protected by the topology of multiferroic vortices using in situ conductive atomic force microscopy, piezoresponse force microscopy, and kelvin-probe ...

Enhanced Coupling Between Soft Ferromagnetism and Displacive Ferroelectricity in the Pb‐Site Modified PbFe1/2Nb1/2O3

Advanced Electronic Materials
Albeit having great potential toward unprecedented type of applications such as magnetoelectric (ME) sensors and memories, practically useful single‐phase multiferroics that show large coupling between ferromagnetism and ferroelectricity at ambient ...

Electric Field Modulation of Interlayer Coupling via Piezostrain in a Synthetic Antiferromagnet

Advanced Science, EarlyView.
Controlling the interlayer exchange coupling (IEC) in synthetic antiferromagnets (SAFs) using an electric field is a promising route toward energy‐efficient spintronic devices. In this study, electric field induced‐strain modulation of IEC in Co/Ru/Co SAF/PMN‐PT is demonstrated.

Stepwise Reduction of Ruthenium and Growth of Magnetic Structure During Hydrothermal Crystallisation of SrRu2O6 from KRuO4

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
In situ neutron powder diffraction data collected while heating the Ru(VII) reagent KRuO4 in the presence of aqueous Sr2+ reveal the crystallisation of a Ru(VI) oxyhydroxide before the expected Ru(V) oxide; at the same time evolution of antiferromagnetism in the final SrRu2O6 product follows the growth of its crystal structure.

Giant Polar Displacements via Strain Relaxation in Itinerant Ferromagnet SrRuO3 Freestanding Films

Advanced Science, EarlyView.
The discovery of substantial Ru off‐centre displacements exceeding 30 pm in SrRuO3 freestanding films is reported, achieved by properly controlling the strain relaxation process to engineer an expanded lattice. The work shows that tailored strain relaxation strategies can be used to design magnetic polar metals with desired electronic states in ...

Exceptionally large room-temperature ferroelectric polarization in the novel PbNiO3 multiferroic oxide

, 2012
We present a study based on several advanced First-Principles methods, of the recently synthesized PbNiO3 [J. Am. Chem. Soc 133, 16920 (2011)], a rhombohedral antiferromagnetic insulator which crystallizes in the highly distorted R3c crystal structure ...

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Independent ferroelectric contributions and rare-earth-induced polarization reversal in multiferroic TbMn2O5

, 2011
Three independent contributions to the magnetically induced spontaneous polarization of multiferroic TbMn2O5 are uniquely separated by optical second harmonic generation and an analysis in terms of Landau theory.
