abstract: Sea bed logging is a new technology being implemented for deep target exploration. In seabed logging, the magnitude of electromagnetic (EM) wave for detection of hydrocarbon reservoir is very important and still remained challenge. New Al transmitter with (Y 3Fe 5O 12 with and without MWCNTs) magnetic feeders was used in a marine scaled tank to enhance the magnetic field strength. Experiments were done in marine lab scale tank to replicate the real seabed environment. Y 3Fe 5O 12 with and with out multiwall carbon nano tubes (MWCNTs) were synthesized by using sol gel-self combustion hybrid method. Samples were sintered at 550C, 750C and 1050C to get the required characteristics of the garnet nanoparticles. Y 3Fe 5O 12 samples with and without MWCNTs were characterized by using XRD, RAMAN, FESEM and Impedance network analyzer. X-ray diffraction results revealed that the best Y 3Fe 5O 12 phase was appeared at the sintering temperature of 1050C. Nanoparticles sizes ranging from 70 to 110 nm were obtained by using sol gel-self combustion hybrid method. Raman results also demonstrate the confirmation of garnet structure of Y 3Fe 5O 12 at sintering temperature of 1050C. Field emission scanning electron microscopy (FESEM) was used to see the morphology of Y 3Fe 5O 12 with and with out MWCNTs composites. Magnetic characterization results illustrates that Y 3Fe 5O 12 with MWCNTs at 1050C has higher Initial permeability (33.302) and high Q-factor (55.104), where as low loss factor (0.0003) was also investigated for Y 3Fe 5O 12 MWCNTs composites. It was observed that by using Y 3Fe 5O 12-MWCNTs polymer composites toroid as magnetic feeders resulted 210 increase in magnetic field strength. © 2011 IEEE.
