The precursor powder was nanocrystalline gamma-Fe2O3, which was synthesized, using DC arc plasma in the oxygen ambient by vapour-vapour interaction in gas phase condensation; at a stabilized arc current of 40 A. This powder was characterized by X-ray diffraction, Transmission Electron Microscopy, Vibrating Sample Magnetometer and Mossbauer Spectroscopy. An increase in directional coercivity was observed in case of films deposited on silicon substrates, which is dramatically significant. Preferred orientation of almost similar sized nanocrystalline magnetic domains in deposited films is evident from the results of X-ray diffraction and Transmission Electron Microscopy results. The preferred alignment of the nanocrystallites seems to be responsible for the significant changes observed in magnetic properties of films.</p>1 aBhave, T., M.1 aBalasubramanian, C.1 aNagar, H.1 aKulkarni, S.1 aPasricha, R.1 aBakare, P., P.1 aDate, Sadgopal, K.1 aBhoraskar, S., V.  uhttps://library.ncl.res.in/content/oriented-growth-nanocrystalline-gamma-ferric-oxide-electrophoretically-deposited-films-001611nas a2200289   4500008004100000022001400041245012700055210006900182260010600251300001400357490000700371520056300378653002200941653003200963653001400995653002701009653000801036100002201044700002001066700002401086700001701110700001901127700001801146700001601164700002201180856011901202       2006                        eng d  a1359-646200aPreparation of gamma-Fe2O3 nanoparticles using DC thermal arc-plasma route, their characterization and magnetic properties0 aPreparation of gammaFe2O3 nanoparticles using DC thermal arcplas  aTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLANDbPERGAMON-ELSEVIER SCIENCE LTDcAPR  a1235-12400 v543 a<p>gamma-Fe2O3 particles were prepared, for the first time, using a direct current thermal arc-plasma route. The powder was characterized using X-ray diffraction, Mossbauer spectroscopy, X-ray photoelectron spectroscopy, chemical analysis, vibrating sample magnetometry C and transmission electron microscopy. The high purity, stoichiometry and spherical morphology of the gamma-Fe2O3 particles (saturation magnetization = 79 emu g(-1) and coercivity = 348 Oe) were confirmed. (c) 2006 Acta Materialia Inc.
