Iron Garnet

Yttrium Iron Garnet (YIG) has been used as an important material in the Circulator/Isolator which is used in RF communication system, mobile phone, and satellite broadcasting, etc. In this study, we investigated the variation of electromagnetic properties of YIG ferrites for Isolator/Circulator application with Zr addition. The YIG ferrites, Y2.1Ca0.9Fe4.4-xV0.5In0.05Al0.05ZrxO12 with x=0, 0.05, 0.1 and 0.2, were prepared by the conventional ceramic sintering process. The Zr-substituted YIG ferrite, Y2.1Ca0.9Fe4.4-xV0.5In0.05Al0.05ZrxO12, showed the highest saturation magnetization (1097 gauss) at x=0.1. Good microwave properties were shown as isolation of 18.60 dB and insertion loss of 0.45 dB at x=0.2. In addition, the ferromagnetic resonance (FMR) linewidth decreased as Zr content increased

The exsolution of magnetite from a substituted Yttrium Iron Garnet, containing an iron excess may lead to a transitional event. This event is characterized hy the formation of a transitional zone at the center of which the magnetite nucleates (Fig.1). Since there is a contrast between the matrix and these zones and since selected area diffraction does not show any difference between those zones and the matrix in the reciprocal lattice, it is of interest to analyze the structure of the transitional zones.By using simultaneously different techniques in electron microscopy, (oscillating crystal method microdiffraction and X-ray microanalysis)one may resolve the ionic process corresponding to the transitional event and image this event subsequently by high resolution technique.
