The Experimentalist's Guide to the Cycloid, or Noncollinear Antiferromagnetism in Epitaxial BiFeO3

Advances in Materials, 2020
Bismuth ferrite (BiFeO3) is one of the most widely studied multiferroics. The coexistence of ferroelectricity and antiferromagnetism in this compound has driven an intense search for electric‐field control of the magnetic order.

Triangular antiferromagnetism on the honeycomb lattice of twisted bilayer graphene [PDF]

Physical review B, 2018
We present the electronic band structures of states with the same symmetry as the three-sublattice planar antiferromagnetic order of the triangular lattice.

Anomalous Antiferromagnetism in Metallic RuO_{2} Determined by Resonant X-ray Scattering. [PDF]

Physical Review Letters, 2018
We studied the magnetic ordering of thin films and bulk crystals of rutile RuO_{2} using resonant x-ray scattering across the Ru L_{2} absorption edge. Combining polarization analysis and azimuthal angle dependence of the magnetic Bragg signal, we have ...

Prospect for Antiferromagnetic Spintronics [PDF]

IEEE Transactions on Magnetics, 2015
Exploiting both spin and charge of the electron in electronic micordevices has lead to a tremendous progress in both basic condensed-matter research and microelectronic applications, resulting in the modern field of spintronics. Current spintronics relies primarily on ferromagnets while antiferromagnets have traditionally played only a supporting role.

High-pressure synthesis and magnetic properties of tetragonal R2BaCuO5 (R = Sm and Eu)

Frontiers in Chemistry, 2023
We report the experimental discovery of a new structural phase of well-known orthorhombic R2BaCuO5 (R = Sm and Eu), exhibiting a tetragonal crystal structure with space group P4∕mbm.

Elasticity and antiferromagnetism of metallic antiferromagnetics

Journal de Physique et le Radium, 1959
If an antiferromagnetic is spontaneously deformed on cooling through the Néel temperature, then the application of an external stress results in a redistribution of domain vectors, e.g. they may rotate or antiferromagnetic domain walls may move. This causes an additional strain component which will be apparent as an anomalous variation of the Young's ...

Itinerant Antiferromagnetism in RuO_{2}. [PDF]

Physical Review Letters, 2016
Bulk rutile RuO_{2} has long been considered a Pauli paramagnet. Here we report that RuO_{2} exhibits a hitherto undetected lattice distortion below approximately 900 K. The distortion is accompanied by antiferromagnetic order up to at least 300 K with a

Coexistence of superconductivity and antiferromagnetism in the Hubbard model for cuprates [PDF]

Physical review B, 2018
Antiferromagnetism and $d$-wave superconductivity are the most important competing ground-state phases of cuprate superconductors. Using cellular dynamical mean-field theory for the Hubbard model, we revisit the question of the coexistence and ...

Room-temperature stabilization of antiferromagnetic skyrmions in synthetic antiferromagnets [PDF]

Nature Materials, 2019
Room-temperature skyrmions in ferromagnetic films and multilayers show promise for encoding information bits in new computing technologies. Despite recent progress, ferromagnetic order generates dipolar fields that prevent ultrasmall skyrmion sizes, and allows a transverse deflection of moving skyrmions that hinders their efficient manipulation ...

Antiferromagnetism Emerging in a Ferromagnet with Gain. [PDF]

Physical Review Letters, 2018
We present a theoretical mapping to show that a ferromagnet with gain (loss) is equivalent to an antiferromagnet with an equal amount of loss (gain). Our findings indicate a novel first-order ferromagnet-antiferromagnet phase transition by tuning the ...
