<p> The magnetic structures of antiferromagnetic manganese
pyrophosphate and copper pyrophosphate have been
determined by single crystal neutron diffraction techniques.
More detailed features of the magnetic structure have been
determined by nuclear magnetic resonance (NMR). A discrepancy
between previous NMR measurements on Mn2P2o7
and the single crystal neutron measurements was resolved by postulating
a low temperature crystallographic phase transition.
Information about the dependence of the transferred hyperfine
interaction upon the separation of the relevant ions
is obtained for Cu2P2o7 from the NMR data and from previously
determined deviations from a higher symmetry phase. The
origin of the magnetic anisotropy energy in Cu2P2o7 is
discussed. </p> / Thesis / Doctor of Philosophy (PhD)
