December 2020: Links relevant to my current activities include darrengoossens.wordpress.com, biotext.com.au/training and stylemanual.com.au.
My most recent publications are textbooks for Year 12 physics. The Physics in Focus series is published by Cengage, and can be discovered here and here, for example.
This worked out ok; here.
November 2020: I'd like to thank the many people that I worked with during my time in science. It was very rewarding and at times exciting and infuriating. I think I did my share of infuriating others, too. That it did not work out in the long term was my own doing; I learned some valuable lessons, but too late. Amongst others, I'd like to offer many thanks, and in some cases apologies, to (in alphabetical order):
These webpages are likely to be updated rarely if ever, and provide a snapshot of business as it was at about the end of 2013. You will find outdated content and dead links, and I do not plan to do anything about it.

Group leader, Darren Goossens, was until recently an Australian Institute of Nuclear Science and Engineering (AINSE) Research Fellow. AINSE provides access to nuclear-related science for Australia-based researchers. They offer post graduate awards as well as providing the link to ANSTO.
Structure of Oxides: Properties found in oxide materials include superconductivity, ordered magnetism, piezoelectricity and multiferroic behaviour. We use a combination of bulk-property studies (dielectric, magnetic and so on) coupled with detailed structural studies using neutron, X-ray and electron diffraction, to try to make the link between structure and function in such materials. Once this relationship is understood, new materials can be 'designed', with new and improved properties.
Magnetism in Two Dimensions occurs in a range of materials, and is of fundamental interest. We are interested in the interrelationship of
critical behaviour, spin dimensionality and the dimensionality of the magnetic
system. The types of magnetic ordering present as a function of applied field, temperature and composition, and
the effect of magnetic mixing and dilution on the properties and structures are the main areas of study. Key tools include magnetometry and neutron diffraction, as the neutron scatters from the magnetic moment of an atom.
ZMC is a program to model diffuse scattering, particularly from flexible molecules. It has been
under steady development.
StrucFact is a program to calculate structure factors for neutron
scattering, both nuclear and magnetic. It is very crude and manual but at least simple. Updated September 2013.
Archives contain source code (Fortran90), some documentation and some executables. zip tar.gz
Brillouin is a trivial program to calculate 'Brillouin magnetic moment as a function of reduced temperature' curves. Updated June 2014.
Archives contain source code (Fortran90), a Linux executable and some sample output. Please see the source code for the details of the paper that I used for the basis of the calculation; it should be referenced if this code is used. tar.gz
Metal Injection Moulding is powder metallurgy manufacturing process and we are examining the kinetics of phase evolution during sintering of the components by using a combination of neutron diffraction and electron microscopy.
