This is our initial response towards preparation of nano-inductors garnet for high operating frequencies strontium iron garnet (Sr 3Fe 5O 12) den oted as SrIG and yttrium iron garnet (Y 3Fe 5O 12) denoted as YIG. The garnet nano crystals were prepared by no vel sol-gel technique. The phase and crystal structure of the prepared samples were identified by using X-ray diffraction analysis. SEM images were done to reveal the surface morphology of the samples. Raman spectra was taken for yttrium iron garnet (Y 3Fe 5O 12). The magnetic properties of the samples namely initial permeability (μ,), relative loss factor (RLF) and quality factor (Q-Factor) were done by using LCR meter. From the XRD profile, both of the Y 3Fe 5O 12 and Sr 3Fe 5O 12 samples showed single phase garnet and crystallization had completely occurred at 900 °C for the SrIG and 950 °C for the YIG samples. The YIG sample showed extremely low RLF value (0.0082) and high density 4.623 g/cm 3. Interesting however is the high Q factor (20-60) shown by the Sr 3Fe 5O 12 sample from 20-100 MHz. This high performance magnetic property is attributed to the homogenous and cubical-like microstructure. The YIG particles were used as magnetic feeder for EM transmitter. It was observed that YIG magnetic feeder with the EM transmitter gave 39 higher magnetic field than without YIG magnetic feeder. © 2011 American Scientific Publishers.
