The study investigated the dependencies of alternating current magnetic susceptibilities of nanocomposite rare-earth titanates on magnetic fields. The results showed that the field dependence of the real part of the susceptibility is approximated by a Cole-Cole formula and is similar to the field dependence of the differential susceptibility.
The dependences of the alternating current magnetic susceptibilities of nanocomposite rare-earth titanates on the magnetic field are investigated. The nanocomposites are prepared in opal matrices with rare-earth titanate particles having a pyrochlore structure. The measurements are performed within the temperature range from 2 to 10 K in magnetic fields up to 30 kOe. It was found that the field dependence of the real part of the susceptibility is approximated by a dependence similar to the Cole-Cole formula and it is close to the field dependence of the differential susceptibility.
