Our new paper titled “Influence of defect thickness on the angular dependence of coercivity in rare-earth permanent magnets” has just been published in the journal Applied Physics Letters. It was a long time coming and the result of much collaborative effort but I am really proud that this work is finally out there. Thank you to all of my co-authors for their input, support and advice. The work shows using micromagnetics simulations and experimental data that there is a direct connection between the coercivity in rare earth permanent magnets and the thickness of the surface defect with reduced anisotropy....

New paper I am pleased to announce our new paper, which can be downloaded from http://arxiv.org/abs/1312.3791 Abstract In the search for rare-earth free permanent magnets, various ideas related to shape anisotropy are being pursued. In this work we assess the limits of shape contributions to the reversal stability using micromagnetic simulations. In a first series of tests we altered the aspect ratio of single phase prolate spheroids, ranging from 1 (sphere) to 20....

In July our paper “System Dynamics models for improved power plant operation” was presented at ICOSC 2013 (The Fourth International Conference on Optimization, Simulation and Control) in Ulaanbaatar by our colleague and friend Bayasgalan Zagdkhorol of Mongolian University of Science & Technology (MUST). The abstract, which shows some of our early results, can be found here. Thank you, Zagdaa, for representing us and our work!
