Noncollinear Magnetism

Hobbs, David LU and Hafner, Jürgen (2006) In Annals of the Marie Curie Fellowship Association 4. p.1-6
Abstract
Recently, a great deal of effort has been focused on

developing the so called “fully unconstrained” approach

to noncollinear magnetism. This approach allows the

magnetization density within a material to be calculated

as a continuous vector variable of position, as opposed to

using the atomic moment approximation (AMA) where a

fixed quantization direction is assumed for a volume filling sphere surrounding each atomic site, i.e., the

constrained approach. In this paper a number of

applications of the method are reviewed. Initially, only

small clusters of Iron (Fe) and Chromium (Cr) atoms

were studied which nicely illustrated some possible

small clusters of Iron (Fe) and Chromium (Cr) atoms

were studied which nicely illustrated some possible

noncollinear magnetic arrangements. However, later

research has been applied to triangular free-standing Cr

and Manganese (Mn) monolayers and overlayers on Cu

substrates. Finally, noncollinear magnetism has been

investigated within the different phases of Mn, including

the complex α-Mn phase, which has been shown

experimentally to have a noncollinear magnetic structure. (Less)
