OOMMF Utilities 1.0

Object Oriented Micromagnetic Framework (OOMMF) is free, portable, extensible public domain micromagnetic program and associated tools, which was developed at the National Institute of Standards and Technology (NIST). OOMMF is very powerful and useful tool which can be thinly configured for different micromagnetic studies, but at the same time, it…

Bloch Point Structure in a Magnetic Nanosphere

Authors: Oleksandr V. Pylypovskyi, Denis D. Sheka, Yuri Gaididei Publication: Phys. Rev. B 85, 224401 (2012), 10.1103/PhysRevB.85.224401 Comments: 8 pages, 7 figures arXiv: http://arxiv.org/abs/1112.2413 The micromagnetic singularity, the so–called Bloch point, can form a metastable state in the nanosphere. We classify possible types of Bloch points and derive analytically the…

Vortex polarity switching by a spin-polarized current

Authors: Jean-Guy Caputo, Yuri Gaididei, Franz G. Mertens, Denis D. Sheka, Publication: Phys. Rev. Lett. 98, 056604 (2007), 10.1103/PhysRevLett.98.056604 Comments: 4 pages, 3 figures arXiv: http://arxiv.org/abs/cond-mat/0607362 The spin-transfer effect is investigated for the vortex state of a magnetic nanodot. A spin current is shown to act similarly to an effective magnetic field…
