Antiferromagnetism in Metals [PDF]
Neutron diffraction studies of chromium and manganese by Shull & Wilkinson have disclosed the existence of a partial antiferromagnetic ordering in these metals, dissimilar in several respects from the antiferromagnetism which occurs in compounds such as MnF 2 and MnO.

Antiferromagnetism in Gd2Ni2Cd
Journal of Magnetism and Magnetic Materials, 1999Abstract Structural, electric and magnetic measurements have been performed on the new rare earth intermetallic compound Gd 2 Ni 2 Cd. It crystallises in the Mn 2 B 2 Al-type structure (space group Cmmm) and undergoes an antiferromagnetic transition at 65 K. Above 70 K the compound follows the Curie–Weiss law with μ =8.03 μ B and θ =+22 K.

A model for an antiferromagnet
Physica, 1973Abstract An exactly solvable model for an antiferromagnet is proposed, which consists of two coupled Van der Waals spin systems with a Heisenberg interaction. The model exhibits a second-order phase transition.

Magnetostatic Modes in Antiferromagnets and Canted Antiferromagnets
Journal of Applied Physics, 1966The resonance frequencies of the magnetostatic modes are calculated for an antiferromagnetic sphere with a dc magnetic field applied along the direction of easy magnetization. For resonance at a fixed frequency, the separations between the various modes are of order 0.2 (2HexHA)½4πM/Hex Oe.

On the Antiferromagnetism of a-FeOOH
physica status solidi (b), 1966AbstractThe Mössbauer effect is measured in natural and synthetic α‐FeOOH samples in an attempt to resolve discrepancies between results reported in the literature. The present results indicate that the deviations can be explained by the presence of water in some of the samples. The Néel temperature is found to be (367 ± 2) °K. The measured temperature

Magnetostriction and antiferromagnetic domains dynamics in helical antiferromagnets
Journal of Magnetism and Magnetic Materials, 1990Abstract Magnetostriction of helical antiferromagnets of the system Zn x Cd 1− x Cr 2 Se 4 is measured by means of film strain gauge spattered at the studied sample. The gauge does not deform the sample under study. The temperature dependences of tetragonal deformations caused by spontaneous exchange striction are measured.

Exchange bias in diluted-antiferromagnet/antiferromagnet bilayers
Journal of Physics D: Applied Physics, 2014The 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.
