Ultrafast spin-polarized current pulses measured in magnetic layers for the first time

BESSY II: Insight into ultrafast spin processes with femtoslicing

An international team has succeeded at BESSY II to elucidate how ultrafast spin-polarized current pulses can be characterized by measuring the ultrafast demagnetization in a magnetic layer system within the first hundreds of femtoseconds. The findings are useful for the development of spintronic devices that enable faster and more energy-efficient information processing and storage.

A Route For More Efficient SOT-MRAM Designs (NTU, TSMC)

A new technical paper titled “Efficient Magnetization Switching via Orbital-to-Spin Conversion in Cr/W-Based Heterostructures” by researchers at National Taiwan University and TSMC. Abstract “A highly efficient spin–orbit torque (SOT) switching mechanism is crucial for the realization of practical SOT magnetic random-access memory (MRAM). This study proposes a Cr/W-based spin current source (SCS) that harvests the sizable orbital current from re…
