Abstract
Nanoparticles of ferrimagnetic NiFe2O4 and antiferromagnetic NiO exhibit a
variety of anomalous magnetic properties. The lower coordination of surface
spins is responsible in both cases for the observed behavior. This conclus
ion is supported by calculations of field-dependent spin distributions in t
hese nanoparticles. (C) 1999 Elsevier Science B.V. All rights reserved.
