Conjugate gradient methods in micromagnetics
J. Fischbacher, A. Kovacs, H. Oezelt +9
Conjugate gradient methods for energy minimization in micromagnetics are compared. When the step length in the line search is controlled, conjugate gradient techniques are a fast a…
Nanoanalytical TEM studies and micromagnetic modelling of Nd-Fe-B magnets
Gregor A. Zickler, Peter Toson, Ahmad Asali +1
We have analysed the influence of the microstructural features, such as intergranular grain boundary (GB) phases and misalignment of the hard magnetic grains, on the optimization o…
Ab-Initio Study on the Hard Magnetic Properties of MnBi
Peter Toson, Ahmad Asali, Gregor A. Zickler +1
We have studied the hard magnetic properties of the low-temperature phase of MnBi with first principle calculations based on the density functional theory. The calculations have be…
Fundamental limits in heat assisted magnetic recording and methods to overcome it with exchange spring structures
Dieter Suess, Christoph Vogler, Claas Abert +3
The switching probability of magnetic elements for heat assisted recording is investigated. It is found that FePt elements with a diameter of 5 nm and a height of 10nm show, at a f…
Calculation of coercivity of magnetic nanostructures at finite temperatures
D. Suess, L. Breth, J. Lee +7
We report a finite temperature micromagnetic method (FTM) that allows for the calculation of the coercive field of arbitrary shaped magnetic nanostructures at time scales of nanose…
Nanostructured Melt-Spun Sm(Co,Fe,Zr,B)7:5 Alloys for High-Temperature Magnets
Sofoklis S. Makridis, George Litsardakis, Kostas G. Efthimiadis +6
High coercivity, the highest for Cu-free 2 : 17 Sm-Co ribbons, has been obtained in as-spun (= 211 kOe) and short time annealed (= 232 kOe) samples of Sm(CobalFe Zr B)7 5 alloys, w…
