Ultrafast control of spin order by linearly polarized light in noncollinear antiferromagnetic metals
J. Kimak, M. Nerodilova, K. Carva +15
The non-thermal optical control of magnetic order offers a promising route to ultrafast, energy-efficient information technologies. Although optical manipulation of magnetism in me…
Sub-nanosecond heat-based logic, writing and reset in an antiferromagnetic magnetoresistive memory
M. Surynek, A. Farkas, J. Zubac +9
Thermal logic aims to create thermal counterparts to electronic circuits. In this work, we investigate experimentally the response of an analog memory device based on a thin film o…
Spin Hall magnetoresistance at the altermagnetic insulator/Pt interface
Miina Leiviskä, Reza Firouzmandi, Kyo-Hoon Ahn +22
The resistance of a heavy metal can be modulated by an adjacent magnetic material through the combined effects of the spin Hall effect, inverse spin Hall effect, and dissipation of…
Picosecond transfer from short-term to long-term memory in analog antiferromagnetic memory device
M. Surynek, J. Zubac, K. Olejnik +9
Previous experiments in compensated magnets have demonstrated a potential for approaching the limit of fastest and least-dissipative operation of digital memory bits. However, the…
Accessing ultrafast spin-transport dynamics in copper using broadband terahertz spectroscopy
JiÅà Jechumtál, Reza Rouzegar, Oliver Gueckstock +10
We study the spatiotemporal dynamics of ultrafast electron spin transport across nanometer-thick copper layers using broadband terahertz spectroscopy. Our analysis of temporal dela…
