摘要	We have successfully prepared magnetic frustrated compound Mg[Ti-2]O-4 by a novel technique of spark plasma sintering. X-ray diffraction confirms that the sample is single phase and the spinel parameter a = 8.504(7) angstrom at the room temperature. The magnetic susceptibility shows that an abnormal drop is exhibited at about 254 K, indicating a magnetic single formation, and that a paramagnetic susceptibility increase which obeys the Curie Law appears below about 150 K, revealing that the number of Ti3+ ions which don't take part in spin dimer is about 2.6%. The resistivity shows a jump at the temperature of 254 K, in agreement with the transition temperature of measurement of the susceptibility. (c) 2006 Elsevier B.V All rights reserved.
