... occur.^2.1

Heisenberg Natural Linewidth and random thermal motion leads to line broadening and thus an overlap of the two energies in this simple regime but the effect is extremely small.

The radioactive source can be replaced by a synchrotron x-ray radiation source, which has certain advantages, particularly in time-dependent effects, but this is beyond the scope of the subject of this thesis.

... magneton^3.1

Derived from three fundamental constants; electronic charge $e$, electronic mass $m$ and Planck's constant $h$, the Bohr magneton is a natural unit of magnetic moment in the same way that $e$ is a natural unit of electric charge.

... jump^3.3

Named after H. Barkhausen who, in 1919, gave experimental evidence of spontaneous reconfiguration of domains as an applied field continuously alters the system's energy balance. These jumps can be small, resulting from localised domain wall movement, or large when associated with the nucleation of domains with reverse magnetisation, for example. The Berkhausen effect gives fine structure to magnetisation curves.

The slight curvature for the ferrimagnet is due to the differing Curie temperatures and interactions for the two types of magnetic atom.
