摘要：
Electronic and magnetic properties of the polycrystalline samples with the general formula CuxFeCr1-xO2 (where 0 < x < 1) have been studied by various techniques. The effects of Cr3+ substitution on the magnetic properties of CuFeO2, as a starting material, were examined by hysteresis measurements. Magnetic studies of the samples were also supported by Magnetic Circular Dichroism measurements. All the samples were determined as showing a magnetic transition peak at characteristic Neel Temperature (T-N) temperature from antiferromagnetic to paramagnetic ordering. Besides, the effect of high external magnetic field (H > 2T) to magnetic ordering were also studied and a change from paramagnetic to AFM at high magnetic fields observed. However, according to the decreasing Cu concentration in the sample, prominent changes both in intensity and in the anti-ferromagnetic ordering structure determined.
