Review paper featured in JPCM highlights of 2014

Monday 16 February, 2015

I am pleased to announce that my paper reviewing atomistic spin models and describing the methods implemented in the VAMPIRE software package has been selected as a highlighted article for 2014 in the Journal of Physics: Condensed Matter. Highlighted articles are selected based on referee endorsements, presentation of outstanding research and popularity and are free to read until the end of 2015. Read more.

Updates and upcoming research in 2015

Sunday 25 January 2015

With the arrival of the New Year I thought it would be a good time to talk about recent updates and my research plans for 2015. Last year was particularly neglectful of this site, but there are a lot of exciting developments upcoming and I will be blogging about these as they occur. Read more.

New paper on ultrafast switching in synthetic ferrimagnets published

Thursday 27 February, 2014

Schematic diagram of all-optical thermally induced magnetic switching

Our new paper published in Applied Physics Letters 104, 082410 (2014) has demonstrated a new possibility for all-optical switching synthetic ferrimagnet, a sandwich of two ferromagnetic materials and a non-magnetic spacer layer. The spacer layer engineers the coupling between the two ferromagnets so that they align opposite to one another. When subjected to an ultrafast laser pulse this structure spontaneously switches its magnetic state representing writing a single bit of data. Read more.

Review of atomistic spin models published

My review of atomistic models has been published today in Journal of Physics: Condensed Matter. 26, 103202 (2014). Computational science is often termed the third pillar of research, beside experiment and theory, due to its ability to take intractable problems and provide solutions closer to experiment than available from purely analytical theory. In order for computational physics to be reliable, it is essential that the methods be reproducible and that other research groups can implement the same algorithms and that they give the same results.

Vampire version 3 released

Wednesday 13 November, 2013

Last week I released the latest version of the vampire atomistic code, which now has an official home at vampire.york.ac.uk and manual. The main enhancements include the ability to run vampire on WindowsTM systems, and a largely re-written user interface, which will hopefully make using the code much more intuitive for everyone.
