The samples were synthesized by using sol gel route. The gel were prepared using nitrates of yttrium and iron for the yttium iron garnet (YIG) and nitrates of bismuth and iron for the bismuth iron garnet (BIG). The raw materials were mixed and dissolved in citric acid and were stirred for 3 months in room temperature until the gel was observed. The X-ray diffraction pattern reveals the cubic structure of YIG and BIG samples at 700°C and 500°C respectively. From the M-H diagrams it was found that the YIG and BIG samples have saturation magnetization, Ms of 27.2 Gs with rectangular hysteresis loop and 24.4 Gs with S hysteresis loop, respectively. It is evident from the FESEM micrographs that the rectangular loop shape (YIG) arises from the homogeneous and rounded microstructure as compared to the inhomogenous and random orientation microstructure (BIG) of the samples. From the Electron diffraction done on Transmission Electron Microscope, both of the samples were shown to be single crystals. © (2009) Trans Tech Publications, Switzerland. date: 2009 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-62149098334&doi=10.4028%2fwww.scientific.net%2fDDF.283-286.406&partnerID=40&md5=d2e8239fa45a359f026991d29e8fbe51 id_number: 10.4028/www.scientific.net/DDF.283-286.406 full_text_status: none publication: Defect and Diffusion Forum volume: 283-28 pagerange: 406-412 refereed: TRUE issn: 10120386 citation: Yahya, N.B. and Koziol, K.K.K. and Mansor, M.K.B.
