Theory of Antiferromagnetism and Antiferromagnetic Resonance Absorption, I [PDF]
Progress of Theoretical Physics, 1951 Resonance absorpiion of microwaves by antiferromagnetic· substanct.~ will be discussed by ex tend\ng KiHeI's theory of ferr.omagnetic resonance absorption. Assuming the model proposed in Part I, it follows that there appears a broad resonance absorption peak below the Curie point for a powder specimen, qualitatively similar to that observed by ...

Antiferromagnetic spintronics [PDF]
Nature Nanotechnology, 2015 Antiferromagnetic materials are magnetic inside, however, the direction of their ordered microscopic moments alternates between individual atomic sites. The resulting zero net magnetic moment makes magnetism in antiferromagnets invisible on the outside.

A Theory of Antiferromagnetism [PDF]
Progress of Theoretical Physics, 1953 based on Heisenberg model is developed by a method which is much more directly the analogue of the original B~the method than Weiss-Li's. By the present method, the calculations can be carried out over all temperatures. Especially, the situation at lower temperatures which is obscure in Weiss·U's papers is made dear.

Antiferromagnetism and Ferrimagnetism [PDF]
Proceedings of the Physical Society. Section A, 1952 The present position of our knowledge of antiferromagnetism, including ferrimagnetism, is reviewed, and some very interesting phenomena concerning the magnetic behaviour of certain ferrites and of pyrrhotite are described and explained.

Antiferromagnetic opto-spintronics: Part of a collection of reviews on antiferromagnetic spintronics [PDF]
Nature Physics 14, 229 - 241 (2018), 2017 Control and detection of spin order in ferromagnets is the main principle allowing storing and reading of magnetic information in nowadays technology. The large class of antiferromagnets, on the other hand, is less utilized, despite its very appealing features for spintronics applications. For instance, the absence of net magnetization and stray fields

Coexistence of Antiferromagnetism and Superconductivity in Electron-doped High-Tc Superconductors [PDF]
Phys. Rev. B 76, 020503 (2007), 2007 We present magnetotransport evidence for antiferromagnetism in films of the electron-doped cuprates Pr$_{2-x}$Ce$_x$CuO$_4$. Our results show clear signature of static antiferromagnetism up to optimal doping x=0.15, with a quantum phase transition close to x=0.16, and a coexistence of static antiferromagnetism and superconductivity for 0.12$\le$x$\le$0.

Concepts of antiferromagnetic spintronics [PDF]
physica status solidi (RRL) – Rapid Research Letters, 2017 Antiferromagnetic spintronics is an emerging research field whose focus is on the electrical and optical control of the antiferromagnetic order parameter and its utility in information technology devices. An example of recently discovered new concepts is the N\'{e}el spin-orbit torque which allows for the antiferromagnetic order parameter to be ...

Anisotropy in antiferromagnets [PDF]
Journal of Applied Physics, 2020 Due to the advent of antiferromagnetic (AF) spintronics, there is a burgeoning interest in AF materials for a wide range of potential and actual applications. Generally, AFs are characterized via the ordering at the Néel temperature (TN), but to have a stable AF configuration, it is necessary that the material has a sufficient level of anisotropy so as

Topological aspects of antiferromagnets [PDF]
Journal of Physics D: Applied Physics, 2021 AbstractThe long fascination that antiferromagnetic materials has exerted on the scientific community over about a century has been entirely renewed recently with the discovery of several unexpected phenomena, including various classes of anomalous spin and charge Hall effects and unconventional magnonic transport, and also homochiral magnetic entities

Strongly correlated antiferromagnetic vanadates
APL Materials, 2023 Antiferromagnetic (AFM) materials have zero net magnetic moments due to the alignment of adjacent magnetic moments antiparallel to each other, which have drawn extensive interest in the field of next generation spintronics, thanks to the merits of ...
