October 2021

We are currently recruiting for students wishing to undertake a PhD in 3D artificial spin-ice structures. For informal enquiries or details of the application process, please contact Dr S Ladak.

August 2021

We are delighted to have been awarded funding to pursue a Leverhulme Trust research project upon ordering in complex 3D magnetic nanostructures.

June 2021

Our latest joint work with Prof Anjan Barman presents the first observation of coherent spin waves in a 3D artificial spin ice system. The work has been published in Nano Letters. The article can be found here

May 2021

Our latest work upon 3D artificial spin-ice (3DASI) has been published in Nature Communications. The study which was carried out in collaboration with theorist Dr Michael Saccone, Los Alamos National Lab, shows that the broken symmetry of a 3DASI surface changes magnetic charge nucleation and propagation.

Poster prize_magnetism2016Congratulations to group members Ifan Williams and Matthew Hunt on winning the best poster prize at Magnetism 2016. The work demonstrates how we are able to fabricate 3D magnetic nanostructures with feature sizes of approximately 500nm. We expect further work to reduce this to approximately 200nm.

Nanoscribe install

Very pleased to announce that our new two-photon lithography system has been installed within our lab and is now operational. The system is capable of fabricating 3D nanostructures down to a feature size of 200nm. The system has been installed within a dedicated class 1000 cleanroom situated within our laboratory. We will be using the system intensively in order to manufacture 3D magnetic nanowires and structures.

Woodpiles

Nanoscribe are here to install the new two-photon lithography system. Acceptance test has been completed and we have written our first 3D nanostructures shown above. The picture shows a 3D woodpile structure with feature size <200nm.
