Paramagnetism and antiferromagnetic interactions in Cr-doped GaN [PDF]

Journal of Physics: Condensed Matter, 2011
We report on the magnetic and structural properties of Cr-doped GaN prepared by ion implantation of epitaxial thin films. Based on a detailed analysis of the magnetometry data, we demonstrate that the magnetic interactions between Cr moments in GaN are antiferromagnetic (AFM).

Energy scale of dielectric coupling in antiferromagnetic insulators

Materials Research Express, 2022
To probe the energy of dielectric coupling between the dipole chains and the quasipolarons based on extension of the polaron concept, dielectric and magnetic properties of antiferromagnetic insulators, namely Ca _4-x Cu _x Ti _4 O _12 (x = 3, 2 and 1 ...

Antiferromagnetic and ferromagnetic spintronics and the role of in-chain and inter-chain interaction on spin transport in the Heisenberg ferromagnet

Scientific Reports, 2021
Spin-transport and current-induced torques in ferromagnet heterostructures given by a ferromagnetic domain wall are investigated. Furthermore, the continuum spin conductivity is studied in a frustrated spin system given by the Heisenberg model with ...

Quantum phases in spin-orbit-coupled Floquet spinor Bose gases

Physical Review Research, 2023
We propose a spin-orbit-coupled Floquet spinor Bose-Einstein condensate (BEC) which can be implemented by Floquet engineering of a quadratic Zeeman field.

Antiferromagnetic superexchange interactions in LaOFeAs

, 2008
5 pages and 7 figures; add the appendix to explain how to determine the nearest and next-nearest Fe-Fe exchange interactions J1 and J2. The overcounting on J1 and J2 in previous version in 2x2 Fe-Fe unit cell with the periodic boundary conditions has been corrected.

Three-state model with competing antiferromagnetic and pairing interactions [PDF]

Physical Review E, 2019
Motivated by the rich phase diagram of the high temperature superconductors, we introduce a toy model with three state variables which can be interpreted as two state particles and holes. The Hamiltonian has a term which favors antiferromagnetism and an additional competing interaction which favors bonding between pairs of antiparallel spins mediated ...

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
