Bulk magnetoelectricity in the hexagonal manganites and ferrites [PDF]

open access: yesNature Communications, 2014
Improper ferroelectricity (trimerization) in the hexagonal manganites RMnO$_3$ leads to a network of coupled structural and magnetic vortices that induce domain wall magnetoelectricity and magnetization neither of which, however, occurs in the bulk. Here we combined first-principles calculations, group-theoretic techniques, and microscopic spin models ...

Solvothermal Fabrication of Trimetallic Oxides NCs: Exploring Their Magnetic and Photocatalytic Characteristics

open access: yesNano Select, Volume 7, Issue 4, April 2026.
A trimetallic NiFe2O4/ZnO/Co3O4 nanocomposite is synthesized via a solvothermal route and thermally tuned by post‐annealing. Structural, optical, and magnetic properties evolve systematically with temperature, enabling efficient sunlight‐driven degradation of mixed organic dyes.

Gram‐Scale Production of Iron Oxide Rubik‐Cube Nanoparticles: New Tools for the Clinical Translation of Magnetic Hyperthermia and Magnetic Particle Imaging

open access: yesAdvanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

open access: yesAdvanced Materials, Volume 38, Issue 16, 17 March 2026.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Anisotropic friction and wear of single-crystal manganese-zinc ferrite in contact with itself [PDF]

open access: yes
Sliding friction experiments were conducted with manganese-zinc ferrite (100), (110), (111), and (211) planes in contact with themselves. Mating the highest-atomic-density directions, (110), of matched crystallographic planes resulted in the lowest ...
