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.
We are delighted to have been awarded funding to pursue a Leverhulme Trust research project upon ordering in complex 3D magnetic nanostructures.
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
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. The article can be found here
Dr Sam Ladak contributed to “The 2021 Magnonics Roadmap”, writing a section upon “Novel Fabrication Techniques for Magnonics”, in collaboration with Adekunle Olusola Adeyeye, Durham University. This has been published in Journal of Physics: Condensed Matter Physics. The article can be found here
Paper published: “Use of Two-photon Lithography with a Negative Resist and Processing to Realise Cylindrical Magnetic Nanowires”, in Nanomaterials. The article can be found here
Review published: “Harnessing Multi-Photon Absorption to Produce Three-Dimensional Magnetic Structures at the Nanoscale”, in Materials Journal. The article can be found here
Sam Ladak gives invited talk at MMM, Las Vegas.
We welcome Edward Harding as a new PhD student.
Very excited to announce that our recent work upon 3D magnetic frustrated lattices has been published in the new Nature Publishing Group journal, Communications Physics. The article can be found here.
Group members present at Intermag 2019, Washington DC
We are pleased to announce that our work in collaboration with Prof Anjan Barman upon time-resolved magnetisation dynamics within 3D tetrapod structures has now been accepted by Nanoscale.
We are pleased to announce that our recent publication on 3D nanostructured micro-lenses has been accepted in Optics Express. This publication was written in collaboration with Prof Peter Smowton. The preprint can be found here.
Our group presents latest work at Magnetism 2018.
We have fully funded PhD studentships available. Please see this link for more details: PhD studentships
We are absolutely thrilled to have received a large award from the Engineering and Physics Research Council in order to improve the resolution of two-photon lithography.
Group member Matthew Hunt presents his work upon 3D magnetic nanostructures at Intermag 2017, Dublin.
We welcome Andrew May to our research group. Andrew will be pursuing a PhD upon 3D magnetic nanowires.
We welcome Lucas Chapuis to the group, who will be working with us over the summer.
Group members have come to IBM Research, Zurich to measure our 3D magnetic nanostructures. We thank Rolf Allenspach and group for his hospitality.
Fully funded PhD position available upon 3D magnetic nanostructures within our laboratory, starting in October 2016. If interested then please send me an email (LadakS at cardiff.ac.uk). Studentship advert can be found here.
Congratulations 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.
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.
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.
