Ultrafast readout of a ferromagnet and antiferromagnet

Time: Wednesday, October 24th, 11:00
Speaker: Chiara CICCARELLI, Cambridge

The possibility to read the magnetisation at picosecond timescales is intriguing, being able to read the Neel vector of an antiferromagnet at these time scales is even more intriguing. In this talk I will discuss three different approaches to achieve this: charge pumping[1,2], the spin Seebeck effect [3] and spin pumping [4].
