dc.description.abstractHigh purity powder samples of EuCrO3 were produced by a combustion reaction technique. The crystalline structure, morphology and magnetic properties were investigated by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry and magnetization measurements. The average particle size was found to be about 30 nm. A weak ferromagnetism due to the canting of the Cr3þ spins was observed below a Neel temperature ( TN) of 172 K, yielding, for a formula unit, 0.01 mB, 2.0 kOe and 0.22 mB for the remanent magnetization, coercivity, and magnetization measured at the highest applied magnetic field (85 kOe), respectively, for T ¼ 5 K. The Cr3þeO2eCr3þ bond angle was determined to be 156.3+ being consistent with the lower value found for TN.
