Ultrafast Néel vector switching
Eddie Ivor Harris-Lee, John Kay Dewhurst, Wenhan Chen +3
We predict ultrafast switching in a chiral anti-ferromagnet that occurs at femtosecond times, nearly 5 orders of magnitude faster than the torque induced nanosecond switching previ…

Giant moment increase by ultrafast laser light
Sangeeta Sharma, Deepika Gill, Jyoti Krishna +3
It is now well established that a few femtosecond laser pulse will induce an ultrafast loss of moment in a magnetic material. Here we show that the opposite effect can also occur:…
