Data Assimilation Method for Experimental and First-Principles Data: Finite-Temperature Magnetization of (Nd,Pr,La,Ce)(Fe,Co,Ni)B
Yosuke Harashima, Keiichi Tamai, Shotaro Doi +8
We propose a data-assimilation method for evaluating the finite-temperature magnetization of a permanent magnet over a high-dimensional composition space. Based on a general framew…
Probability distribution of substituted Titanium in RT12 (R = Nd, Sm, T = Fe, Co) structures
Connor Skelland, Thomas Ostler, Samuel Westland +11
We investigated the atomic fill site probability distributions across supercell structures of RT12-xTi (R=Nd, Sm, T=Fe, Co). We use a combined molecular dynamics and Boltzmann dist…
On the limits of coercivity in permanent magnets
J. Fischbacher, A. Kovacs, H. Oezelt +14
The maximum coercivity that can be achieved for a given hard magnetic alloy is estimated by computing the energy barrier for the nucleation of a reversed domain in an idealized mic…
Influence of defect thickness on the angular dependence of coercivity in rare-earth permanent magnets
Simon Bance, Harald Oezelt, Thomas Schrefl +12
The coercive field and angular dependence of the coercive field of single-grain NdFeB permanent magnets are computed using finite element micromagnetics. It is shown t…
Grain-size dependent demagnetizing factors in permanent magnets
Simon Bance, Bernhard Seebacher, Thomas Schrefl +10
The coercive field of permanent magnets decreases with increasing grain size. The grain size dependence of coercivity is explained by a size dependent demagnetizing factor. In Dy f…
