Abstract
Ferrite samples of Mn0.5Ni0.1Zn0.4NdxFe2-xO4 (xâ¯=â¯0.0, 0.01, 0.02, 0.05, 0.075 and 0.1) have been prepared by usual ceramic method. The temperature and composition dependences of the dc electric resistivity (Ïdc) were studied. The frequency and composition dependences of the ac electric resistivity (Ïac) and dielectric parameters (dielectric constant ε' and dielectric loss ε'') have been investigated. Ïdc was found to decrease with temperature for all samples while it increases with increasing Nd3+ concentration. On the other hand, Ïac and the dielectric properties were found to decrease with increasing the frequency while Ïac increases and both ε' and ε'' decrease with increasing Nd3+ concentration. These results were explained by the Maxwell-Wagner two-layer model and Koops's theory. The improvement in dc and ac electric resistivities shows that these prepared materials are valid for decreasing the eddy current losses at high frequencies, so they can be used in the fabrication of multilayer chip inductor (MLCI) devices.
