Abstract
The pyrophosphate of CuFeP 2O 7 was synthesized through one step-thermal synthesis at 500 °C using the mixing of copper carbonate, iron metals and phosphoric acid. FTIR and XRD results indicate the dominant feature of pyrophosphate (P 2O 7 4−) anion and a pure monoclinic phase with space group C 2h 6 ( Z = 4), respectively. The crystallite size of 25 ± 9 nm for the CuFeP 2O 7 was estimated by X-ray line broadening. Room temperature magnetization result shows ferromagnetic behavior of the CuFeP 2O 7 powder, having hysteresis loop in the range of ± 10,000 Oe with the specific magnetization value of 1.57 emu g − 1 . This property is important for specific application and is presented for the first time.
