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. For example, the antiferromagnetic memory bit cell can act as a neuron‐like pulse‐counter able to record thousands of pulses of lengths spanning eight orders of magnitude, as shown in the figure on the cover and discussed by Gomonay et al. (see their Review @ RRL, article no. 1700022 ). The range of unique characteristics including the nonvolatility, radiation and magnetic‐field hardness, no fringing stray fields, THz spin‐dynamics, or the neuron‐like memorylogic functionality make antiferromagnetic spintronics one of the new concepts prone to make a mark in the “More than Moore” technologies, as discussed in the contributions to this Focus Issue.
