IOP Postgraduate Techniques Workshop

IOP2014Logo

This years IOP magnetism techniques workshop for postgraduate students closes today after a packed two day program. The workshop is mainly based around various experimental techniques but with a smidgen of theory thrown in for good measure. The workshop takes place each year close to christmas and is a good opportunity to meet new students and academics involved in magnetism and to see the wide range of skills and techniques the UK has. The social program usually includes a christmas dinner and festive beer or two on the first night. Further information can be found at this link. My slides can be found here.

IOP Postgraduate Magnetic Techniques Workshop

 

The 2013 “Postgraduate Magnetic Techniques Workshop” organised by the Insitute of Physics is taking place today. It is a workshop to provide introductory training in key experimental and theoretical techniques used in magnetic research, aimed at new postgraduate students and research fellows new to magnetic research. My talk will be on the atomistic spin dynamics model and how it can be used to describe magnetization dynamics in the femtosecond regime. I will focus on how the model is constructed and how it is being used to compare to experimental observations. The talk will be available on the conference presentations page.

Ultrafast Magnetism Conference

The first Ultrafast Magnetism Conference (UMC) was held last week in Strasbourg, France. A week focused on magnetism on the sub-picosecond timescale. Talks from both experimental and theoretical groups included talks on laser induced magnetization dynamics, THz stimulation and ultrafast magneto-acoustics.

This meeting was a huge success with over 150 participants from all over the world and a large number of invited talks. The format was a single session talks and posters so that all participants could see everything on offer. The single session format promoted a comfortable environment in which the audience could ask questions and discuss things amongst themselves.

I gave a contribution based on the thermally induced switching phenomena in GdFeCo, recently accepted to Nature Scientific Reports (the preprint can be found on arXiv). This work by Joe Barker shows that the thermally induced switching is caused by the excitation of a two magnon bound state. This bound state is possible when sufficient energy is provided to excite two spinwave bands. This lays out a criteria for ultrafast switching with heat to occur, which Joe tested using the atomistic spin model.

The second Ultrafast Magnetism Conference will take place in 2015 in Nijmegen, where I am sure the event will be even larger and the talks will be equally as interesting.
