説明
In this study, the lattice distortion in the NiZnCu ferrite co-fired with silver (Ag) was evaluated by X-ray diffraction (XRD) using the synchrotron radiation source. The simplified multilayer chip inductor (MLCI) with ∼1.3 mm of width, ∼1.98 mm of length and ∼0.54 mm of height was fabricated by a conventional multilayering technique. Synchrotron experiments were carried out at BL10XU beam line in the SPring-8. It was found that the lattice constant of the ferrite varied depending on place and the value closer to the sample centre (closer to the internal Ag conductor) was larger than one from the edge. The ferrite co-fired at higher temperature also shows larger lattice constant than one at lower temperature. This result is an evidence to show that the lattice of the ferrite has been distorted through the co-firing with Ag and it is enhanced by the higher sintering temperature.
