A combination of μSR and17O nuclear quadrupolar μLCR has been used to obtain
detailed information on the muon site in YBa2Cu3O7. The rms magnitude of the
nuclear dipolar fields in YBa2Cu3O7 enriched with 38%17O is about twice that in
the natural16O sample. In addition the17O μLCR spectrum shows that the electric
field gradient tensor at the oxygen closest to the muon is almost equal to that

Magnetic Properties of Nanoparticles of Antiferromagnetic Materials - 2002

The magnetic properties of antiferromagnetic nanoparticles have been studied by
Mössbauer spectroscopy and neutron scattering. Temperature series of Mössbauer
spectra of non-interacting, superparamagnetic hematite nanoparticles were fitted
by use of the Blume-Tjon relaxation model. It has been found that the magnetic
anisotropy energy constant increases significantly with decreasing particle
size.... hiện toàn bộ
