dc.descriptionThe Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.en_US
dc.description.abstractEffect of Sr substitution on structural, magnetic and electrical properties of LaFeO3 perovskite oxides has been studied. Using the selected Sr doping content (x) from 0.0 to 1.0, perovskite La1-xSrxFeO3 nanopowder was synthesized by sol-gel auto-combustion method, followed by calcination at 900 C for 2 h. The synthesized powder was pressed into disks at room temperature and then the disk samples were sintered at 1200 C for 12 h to obtain a single-phase compound formation and uniaxial compaction. The influence of Sr doping on the phase formation, morphology, ferroelectric and magnetic properties was investigated. The phase formation of the sample changes from orthorhombic at low Sr doping through rhombohedral to cubic for Sr-rich sample as the stoichiometry approached SrFeO3. The grains of La1-xSrxFeO3 ceramics revealed an irregular polyhedron shape. SEM-EDS mapping analysis also exhibited the uniform distribution of all elements. The direct energy gap (Eg) was found to decrease with increasing amounts of Sr doping. Moreover, the La0.6Sr0.4FeO3 ceramic exhibited ferromagnetic behavior with saturated magnetization (Ms) of 0.305 emu/g at room temperature.en_US
