Gm. Sutariya et al., INFRARED AND AC-SUSCEPTIBILITY STUDIES OF MN SUBSTITUTED FERROFLUID, Indian Journal of Pure & Applied Physics, 32(6), 1994, pp. 485-488
Infra-red and ac-susceptibility studies of Mn-substituted ferrofluid w
ere undertaken. The result of infra-red suggest that oleic acid coatin
g is complete and no free radicals were observed. Ac-susceptibility sh
ows a peak at 150K and a theoretical treatment was given to explain th
is behaviour.
