"Dependence of dielectric behaviour of Mn-Zn ferrite on sintering temperature",
Journal of Materials Science, vol. 36, issue 20, pp. 5031 - 5035, 2001.
AbstractThe dielectric constant of Mn-Zn ferrite was measured at different temperature and frequencies as a function of sintering temperature ranging from 1200°C to 1400°C at heating rate of 6°C/min. The resistivities as well as Seebeck coefficient were measured in the same range of temperature. More than one type of polarization is expected to vary the dielectric constant. Hoping mechanism was the predominant one in conduction processes. The grain size was calculated from X-rays and SE micrographs and it was found to decrease with increasing sintering temperature.

"Dependence of exchange interaction constant on organic group and halogen ions of organic complexes",
Journal of Materials Science Letters, vol. 20, issue 8, pp. 725 - 728, 2001.
AbstractOrganic group and halogen ions of organic complexes were recrystallized using ethanol. The obtained crystals are washed in a solution of ethanol;ether in ratio of 1:2, dried and ground to fine powdered. Magnetic susceptibility was measured using the conventional Gouy's method, in the temperature range of 78 K up to near the melting point of each sample. The resulting data was analyzed in detail.
