Post-doctoral research associate in ultrafast magnetic switching; TWISST

Post-doctoral research associate in ultrafast magnetic switching (TWISST) – 0766-25

Lancaster University invites applications for a Post-Doctoral Research Associate to work in ultra‑fast magnetism and THz‑driven spin switching. The post is funded by the EPSRC grant TWISST:
Terahertz wave induced spin switching technology.

TWISST aims to develop the scientific understanding needed to create a new generation of magnetic memory‑devices characterised by very low energy consumption and switching times of one trillionth of a second. To achieve this we will generate an ultrashort light pulse at THz frequencies, strong enough to induce switching of the magnetic order parameter, representing the elementary act of writing a bit of information.

As THz photons exactly match the excitation energy, this represents the optimally energy efficient switching regime, avoiding the localised heating that plagues current energy assisted data storage schemes. We will explore experimentally and theoretically manipulation of magnetic order by the strong THz pulse which can modulate the spin‑orbit and exchange interactions, which are responsible for magnetic ordering. We will focus and concentrate intense THz radiation with an antenna onto a magnet, to switch a nanoscale magnetic bit.

We will calculate the antenna response and associated magnetic dynamics to inform the antenna design achieving the most efficient coupling between THz phonons and magnetic order.

The position offers access to state‑of‑the‑art ultrafast laser facilities and challenging research projects at the interface of photonics and magnetism. There will be opportunities for travel and collaborative work with national (University of Manchester) and international (University of Regensburg, Forschungszentrum Jülich, Free University of Berlin) partners.

• Duration: up to 24 months, available immediately.
