Ultrafast and Ultralow‐Power Voltage‐Dominated Magnetic Logic

Advanced Logic Gates for Ultrafast Network Interchanges

By overcoming speed bottlenecks from electronic switching as well as optical/electronic conversions, all-optical logic gates can permit further exploitation of the nearly 40THz of bandwidth available from optical fibers. We focus on the use of optical solitons and alloptical logic gates to implement ultrafast "interchanges" or switching nodes on packet networks with speeds of 100Gbit/s or great...

Ultrafast photo-magnetic recording in transparent medium

Ultrafast optical encoding of magnetic resonance

Temporal resolution in magnetic resonance imaging (MRI) is limited by the time required to encode the position of spins using time-varying (10–100 ms) magnetic field gradients. Here, we demonstrate spatial encoding of MRI images in a time that is three orders of magnitude shorter than what is possible by conventional gradient encoding techniques. Our method exploits the chemically induced dynam...

Ultrafast optical excitation of magnetic skyrmions

Magnetic skyrmions in an insulating chiral magnet Cu2OSeO3 were studied by all-optical spin wave spectroscopy. The spins in the conical and skyrmion phases were excited by the impulsive magnetic field from the inverse-Faraday effect, and resultant spin dynamics were detected by using time-resolved magneto-optics. Clear dispersions of the helimagnon were observed, which is accompanied by a disti...
