Antiferromagnet with two coupled antiferromagnetic sublattices in a magnetic field [PDF]
Journal of Physics: Condensed Matter, 2011 We discuss the magnon spectrum of an antiferromagnet (AF) in a magnetic field $h$ consisting of two interpenetrating AF sublattices coupled by the exchange interaction at T=0. One-ion easy-plane anisotropy is also taken into account. We calculate using the 1/S expansion the gap in the spectrum which is a manifestation of the order-by-disorder effect in

Antiferromagnetic cavity optomagnonics [PDF]
Physical Review Research, 2020 Currently, there is a growing interest in studying the coherent interaction between magnetic systems and electromagnetic radiation in a cavity, prompted partly by possible applications in hybrid quantum systems. We propose a multimode cavity optomagnonic system based on antiferromagnetic insulators, where optical photons couple coherently to the two ...

Half-Metallic Antiferromagnets [PDF]
Physical Review Letters, 1995 This Letter discusses the possibility of realizing half-metallic antiferromagnets, i.e., systems with 100% spin polarization of the conduction electrons without showing a net magnetization. The predictions are based on electronic structure calculations using the local density approximation.

Anomalous Hall antiferromagnets
Nature Reviews Materials, 2022 The Hall effect, in which current flows perpendicular to an applied electrical bias, has played a prominent role in modern condensed matter physics over much of the subject's history. Appearing variously in classical, relativistic and quantum guises, it has among other roles contributed to establishing the band theory of solids, to research on new ...

Antiferromagnetic magnonic crystals [PDF]
Physical Review B, 2015 We describe the features of magnonic crystals based upon antiferromagnetic elements. Our main results are that with a periodic modulation of either magnetic fields or system characteristics, such as the anisotropy, it is possible to tailor the spin wave spectra of antiferromagnetic systems into a band-like organization that displays a segregation of ...

Advanced Engineering Materials, EarlyView.This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Diluted Graphene Antiferromagnet [PDF]
Physical Review Letters, 2007 We study RKKY interactions between local magnetic moments for both doped and undoped graphene. We find in both cases that the interactions are primarily ferromagnetic for moments on the same sublattice, and antiferromagnetic for moments on opposite sublattices.

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Itinerant antiferromagnetism in FeGe2 [PDF]
Physica B: Condensed Matter, 1997 FeGe_2, and lightly doped compounds based on it, have a Fermi surface driven instability which drive them into an incommensurate spin density wave state. Studies of the temperature and magnetic field dependence of the resistivity have been used to determine the magnetic phase diagram of the pure material which displays an incommensurate phase at high ...
