User Calls

1st May 2020 – 31st October 2020

Due to uncertainty surrounding Coronavirus, the call deadline has currently been extended to 30th April 2020.

We write to inform you of the second call for proposals for use of the Exeter Time Resolved Magnetism (EXTREMAG) facility in the period 1st May 2020 to 31 October 2020.  We realise that it is very difficult to plan any travel at the present time and we will react to the changing circumstances when decisions need to be made about allocation and scheduling.  However, we can at least begin the proposal process.

The supporting EPSRC grant for EXTREMAG ends on 30th of April, so that user charges will be applicable from May onwards.  We hope that it will be possible to support some users who are unable to pay the user charges, but priority will be given to users who are able to pay in order to secure the future of the facility.  The rates are as follows:

1/5/2020 – 31/7/2020

Supported by the Senior Experimental Officer: £917 per day, inc VAT

Unsupported: £324 per day, inc VAT

31/7/2020 – 31/10/2020

Supported by the Senior Experimental Officer: £945 per day, inc VAT

Unsupported: £334 per day, inc VAT

Liquid helium

Additional charges apply to use of liquid Helium.

Unsupported user access

Please note that we will only allow unsupported access to users who have already undertaken induction and training and accumulated sufficient experience of running their intended experiment.  If experienced users propose to try a modified set up that requires support from the SEO, then please allow for enough days at the supported rate.

Available apparatus

(i) Wide field static Kerr microscopy, either at room temperature or low temperature, and with either in-plane or out-of-plane magnetic field in each case.  A pulsed laser optical pump or electrical probes are available for this instrument on request and subject to specific requirements.

(ii) Time resolved scanning Kerr microscopy at room temperature, with either picosecond pulsed field excitation, microwave field excitation, or quasi-dc excitation.  Samples require either an integrated microscale waveguide device for efficient excitation, or else samples can be placed onto a PCB waveguide for weaker excitation.

(iii) All optical pump-probe measurements, at low in-plane or out-of-plane field (<1 T) but variable temperature (4 – 300 K), at fields up to 5 T out-of-plane and variable temperature (4 – 300 K), or at high field up to 10 T out-of-plane.

(iv) THz emission and absorption spectroscopy at room temperature and low field (<0.1 T), or at high field up to 10 T out-of-plane.

Please address any questions about apparatus and the feasibility of different types of measurement to the EXTREMAG mailbox at

The EXTREMAG proposal form can be downloaded by following the link.  The scientific case should not exceed 1 page in length after completion in 12 point Calibri font and including any figures and references.  Please submit your completed form in PDF format by 31st March.
