Solving complex tasks in a modern information-driven society requires novel materials and concepts for energy-efficient hardware. Antiferromagnets offer promising platform seeking such approaches due to their exceptional features: low power consumption possible high integration density are desirable information storage processing or applications unconventional computing. Among antiferromagnets, CuMnAs stands out atomic-level scalable magnetic textures, analogue multilevel capability, the...
Abstract Antiferromagnetic CuMnAs thin films have attracted attention since the discovery of manipulation their magnetic structure via electrical, optical, and terahertz pulses, enabling convenient approaches for switching between magnetoresistive states film information storage. However, and, thus, efficiency can be affected by morphology growth defects. In this study, properties are investigated probing asymmetrical growth‐related uniaxial anisotropy electric conductivity contact‐free...
We demonstrate that epitaxial thin film antiferromagnet Mn2As exhibits the quench-switching effect, which was previously reported only in crystallographically similar antiferromagnetic CuMnAs films. Quench switching shows stronger increase resistivity, reaching hundreds of percent at 5K, and significantly longer retention time metastable high-resistive state before relaxation towards low-resistive uniform magnetic state. Qualitatively, show analogous parametric dependence magnitude signal....
