CMP Seminar - Peter Baker (ISIS): Elevated Curie Temperature in Doped EuO
EuO is an archetypal ferromagnetic semiconductor and has been widely studied because it offers the ability to control spin-polarized electrical currents. This possibility is limited by the low Curie temperature, Tc=69K, of pristine EuO, but electronic doping by chemistry or the application of pressure can more double Tc. Explaining why Tc increases has been controversial, with three models put forward
We have studied thin-film samples of chemically-doped EuOx [1] and (Eu,La)O [2] with low energy muon spectroscopy to investigate the microscopic magnetic behaviour around Tc. In this talk I will present how this work has allowed us to rule out two of the three possible explanations of the Tc increase and discuss the potential for forming 2DEG interfaces with EuO to accentuate the effect.

UKRI Deadlines
Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.
The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:
EPSRC Post Doctoral Fellowship
