Magnetic properties, relaxation, and quantum tunneling in CoFe2O4 nanoparticles embedded in potassium silicate

# metadata.dc.description.abstract[].value
We report magnetic properties and magnetic relaxation phenomena in a sample comprised of nanocrystalline
CoFe2O4 ~;97%!1g-Fe2O3 ~;3%! and polymer in potassium silicate ~as magnetic glass! nanoparticle systems
in which two very different barrier distributions contributed to the relaxation behavior. We have demonstrated
experimentally that only energy barrier distributions and the thermal activation process could not account for
a plateau in the viscosity data at low temperatures. Quantum tunneling of magnetization is suggested below ;3
K.
