Antiferromagnetism

Advances in Physics, 1955
The ground state of a lattice with one electron per atom and antiferromagnetic interactions between nearest neighbours only is examined by a variational method similar in principle to the treatments by Hulthén (1938) and Kasteleijn (1952) of the linear-chain problem. The calculation involves a statistical problem which is shown to be exactly equivalent

Antiferromagnetic relaxation in orthorhombic antiferromagnets

Physica B+C, 1976
Abstract The time evolution of the autocorrelation function ( M Z , M Z ( t )), where M Z denotes the total uniform magnetization along the easy axis, is investigated in the two orthorhombic antiferromagnets CuCl 2 · 2H 2 O and LiCuCl 3 · 2H 2 O.

Coherent antiferromagnetic spintronics

Nature Materials, 2023
Antiferromagnets have attracted extensive interest as a material platform in spintronics. So far, antiferromagnet-enabled spin-orbitronics, spin-transfer electronics and spin caloritronics have formed the bases of antiferromagnetic spintronics. Spin transport and manipulation based on coherent antiferromagnetic dynamics have recently emerged, pushing ...

Magnetic coupling across the antiferromagnetic–antiferromagnetic interface

Journal of Physics D: Applied Physics, 2021
Abstract We investigate the magnetic coupling across the antiferromagnetic–antiferromagnetic (AFM–AFM) interface for the prototypical CoO-NiO bilayer system where the bulk Néel temperature (T N ) of NiO is higher than that of CoO ...

Antiferromagnetic Potts models

Physical Review Letters, 1989
We present a study of the antiferromagnetic Potts model in two and three dimensions, using a new method of Monte Carlo simulations, which enables us to perform simulations with greatly improved efficiency. Illustrating the method for the three-state model, we have obtained new results for the entropy and critical exponents in two and three dimensions ...

Random Antiferromagnetic Chain.

Physical Review Letters, 1979
The quantum spin-\textonehalf{} Heisenberg antiferromagnet in one dimension with randomly distributed coupling constants is solved approximately. Ground-state energies and low-temperature properties are obtained for several distributions of coupling constants (including both singular and nonsingular distributions).

Antiferromagnetic resonances and magnetization of a canted antiferromagnet

Journal of Magnetic Resonance, 2004
A two-sublattice model has been applied to a canted antiferromagnet including both Dzyaloshinsky-Moria interaction and double-exchange. Static magnetization and frequencies of the antiferromagnetic resonances (AFMR) were calculated for static magnetic fields along the principal crystallographic axes of an orthorhombic crystal. The experimental data for

Exchange bias in diluted-antiferromagnet/antiferromagnet bilayers

Journal of Physics D: Applied Physics, 2014
The hysteresis-loop properties of a diluted-antiferromagnetic (DAF) layer exchange coupling to an antiferromagnetic (AF) layer are investigated by means of numerical simulations. Remarkable loop shift and coercivity enhancement are observed in such DAF/AF bilayers, while they are absent in the uncoupled DAF single layer.
