Synthetic antiferromagnetic spintronics [PDF]
Nature Physics, 2018 Spintronic and nanomagnetic devices often derive their functionality from layers of different materials and the interfaces between them. This is especially true for synthetic antiferromagnets - two or more ferromagnetic layers that are separated by metallic spacers or tunnel barriers and which have antiparallel magnetizations.

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 ...

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 ...

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.

Metallic antiferromagnets [PDF]
Journal of Applied Physics, 2020 Antiferromagnetic materials have recently gained renewed interest due to their possible use in spintronics technologies, where spin transport is the foundation of their functionalities. In that respect, metallic antiferromagnets are of particular interest since they enable complex interplays between electronic charge transport, spin, optical, and ...

Dynamic magnetostriction for antiferromagnets [PDF]
Physical Review B, 2019 In this paper we study the switching properties of the dynamics of magnetic moments, that interact with an elastic medium. To do so we construct a Hamiltonian framework, that can take into account the dynamics in phase space of the variables that describe the magnetic moments in a consistent way.

Electrical switching of an antiferromagnet [PDF]
Science, 2016 Manipulating a stubborn magnet Spintronics is an alternative to conventional electronics, based on using the electron's spin rather than its charge. Spintronic devices, such as magnetic memory, have traditionally used ferromagnetic materials to encode the 1's and 0's of the binary code.

Antiferromagnetism and superconductivity in [PDF]
Journal of Physics: Condensed Matter, 1998 The short ranged antiferromagnetism recently seen in UPt_3 is proved incompatible with two dimensional (2D) order parameter models that take the antiferromagnetism as a symmetry breaking field. To adjust to the local moment direction, the order parameter twists over very long length scales as per the Imry-Ma argument.

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, optical or other means of control of the antiferromagnetic order parameter and its utility in information technology devices. An example of recently discovered new concepts is the Néel spin–orbit torque which allows for the antiferromagnetic order parameter to
