OOMMF User's Guide, Version 1.0

September 1, 1999
Author(s)
Michael J. Donahue
This manual describes OOMMF (Object Oriented Micromagnetic Framework), a public domain micromagnetics program developed at NIST. The program is designed to be portable, flexible, and extensible, with a user-friendly graphical interface. The code is written

Measurement and Standards for Computational Science and Engineering

March 1, 1999
Author(s)
Ronald F. Boisvert, J L. Blue, Daniel W. Lozier, William F. Mitchell, Roldan Pozo, Michael J. Donahue, Donald G. Porter
This report describes current work within ITL on the development of measurement and standards technology to improve the practice of computational science and engineering.

A Variational Approach to Exchange Energy Calculations in Micromagnetics

June 1, 1998
Author(s)
Michael J. Donahue
This paper presents a magnetization interpolation method for micromagnetic exchange energy calculations using a variational procedure to relax spins on a supplemental (refined) lattice. The approximations implicit in standard micromagnetic discretization

Micromagnetic Computational Standard Problem (Abstract)

April 1, 1997
Author(s)
Robert D. McMichael, Michael J. Donahue
Proposed solutions to a standard problem in micromagnetics that were collected anonymously from a number of researchers using a variety of computational techniques are presented. This is the first time that a problem in micromagnetics has been attempted by

Magneto-Optical Indicator Film Study of the Magnetization of a Symmetric Spin Valve

September 1, 1996
Author(s)
Valerian I. Nikitenko, V S. Gornakov, L M. Dedukh, Yury P. Kabanov, A F. Khapikov, Lawrence H. Bennett, P J. Chen, Robert D. McMichael, Michael J. Donahue, L Swartzendruber, Alexander J. Shapiro, H J. Brown, William F. Egelhoff Jr.
A magneto-optical indicator film (MOIF) technique is used for direct experimental study of the magnetization reversal process in a symmetric NiO/Co/Cu/NIFe/Cu/Co/NiO spin valve. It is shown for the first time that the reversal of the free center layer

Magneto-Optical Indicator Film (MOIF) Microscopy of Granular and Layer Structures (Abstract)

April 1, 1996
Author(s)
Valerian I. Nikitenko, V S. Gornakov, L M. Dedukh, A F. Khapikov, Lawrence H. Bennett, Robert D. McMichael, L Swartzendruber, Alexander J. Shapiro, Michael J. Donahue, V N. Matveev, V I. Levashov
We report on the possibilities of application of magneto-optical indicator film (MOIF) technique for visualization and direct experimental study in real time of the magnetization processes and nondestructive characterization of the quality of magnetic thin
