Dr Sam Ladak – Lab Leader

I completed my PhD from the University of Exeter in 2006. The project involved the fabrication and characterisation of magnetic tunnel junctions. After this I carried out a year in industry at Seagate technology, designing and prototyping magnetic read-heads. In 2007 I decided to go back to academia and took up postdoctoral positions at the University of York and then Imperial College where I remained for four years.

In 2012, I was awarded a personal chancellors (SBP) fellowship within the School of Physics and Astronomy with the aim of establishing a research group within the emerging field of 3D nanomagnetism. Today, the focus of my work is upon 3D magnetic nanostructure fabrication and characterisation using non-linear optical techniques.

Over the past several years I have secured > £1.2M of external (EPSRC) funding as well as small grants from the Royal Society, Welsh Crucible and Cardiff.

I routinely work with other academics from other leading universities (Exeter, Bristol, Southampton) as well as large international research labs (eg. IBM Zurich).

I completed my PhD under Dr Sam Ladak in 2018, working on the fabrication and measurement of 3D magnetic nanostructures. I am now currently working as a postdoctoral research associate  on an EPSRC funded project. My main area of expertise is in using the magneto-optical Kerr effect (MOKE)  to probe  3D nanostructured samples fabricated within our laboratory.

I finished my undergraduate degree at Cardiff in 2017 where my final year project focused on 3D micromagnetic simulations. After graduation I joined the group as a PhD student to continue this work alongside fabricating 3D magnetic nanowires for racetrack memory applications using two-photon lithography. My main area of expertise is in micro magnetic modelling using various packages.  Outside of my PhD, I am a keen amateur photographer and an avid musician.

My name is Joe, I am currently an MSc student  working on a summer research project to improve magnetometry upon 3D magnetic nanostructures. I will be starting an EPSRC funded PhD project in October and will further be using two-photon lithography to create 3D magnetic nanostructures and artificial biological structures under the supervision of Dr Ladak and Professor Langbein.
