Micromagnetic modelling for materials design.
We can provide Micromagnetic Modelling services using our own modelling software. Our expertise in this are provided by Gino Hrkac, who has published many papers using this methodology and even designed his own modelling package.
Our team member Gino Hrkac has used the aforementioned Micromagnetics package to perform simulations for various high profile companies such as Seagate, particularly in the development of the HAMR drive technology.
Molecular Dynamics modelling using LAMMPS or GULP.
We have 12+ years experience in Molecular Dynamics simulations using primarily LAMMPS or GULP. Our capabilities cover a wide range including surface energies, probable grain shapes, dopant/ substitution positions, melting temperatures, and stress/strain calculations.
Dr Skelland has investigated the probanle grain shapes of FePt L10 at single to double digit nanometer sizes. These grains have applications in next generation Hard Disk Drives, and their shape is important for modelling their magnetic properties.
The work is the subject of an abstract and presentation in MMM/Intermag 2022.
Lattice dynamics simulations using GULP.
We have a combined 12+ years experience in Lattice Dynamics calculations using GULP and can calculate vibrational modes of crystals, perform high accuracy minimum energy calculations, and calculate the elastic constants of a material.
During the start of his PhD our team member, Connor Skelland, used this methodology to predict the best dopant positions for Titanium. By comparing various dopant positions in the crystal lattice he was able to predict the likelihood of dopants filling desirable spots, and report on the crystal lattice expansion associated with various dopant positions.
Specific modelling, and numerical solutions to physics problems.
We can provide computational modelling for all kinds of bespoke systems. With over 18 years experience in multi-scale modelling of magnetic materials with applications in spintronics, energy harvesting, permanent magnets in automotive, and blue sky research in magnetic spin ice structure for magnetic cryptography, we are confident we can provide you with expert knowledge and modelling to suit your needs.
Prof. Hrkac has been working on an analytical model that predicts the formation of crystalline twins within grains.
