Microrod-Structured Co-Mn Compound and Its Magnetic Property

Abstract

The Co-Mn compound with a microrod structure in length of 50–150 μm and diameter of 1–3 μm was firstly prepared through a convenient hydrothermal method. The composition, structure, and morphology of the as-prepared products were characterized by electron microscopy, energy-dispersive X-ray spectrum (EDS), inductively coupled plasma mass spectroscopy (ICP-MS), and X-ray diffraction (XRD). Consequently, the formula of the microrods could be determined as Co₉MnP₄O₁₁. In addition, the magnetic property measured by vibrating sample magnetometer (VSM) under room temperature showed that the saturation magnetization (M _s), remanent magnetization (M _r), and coercivity (H _c) of this microrod are 2.98 emu/g, 0.057 emu/g, and 41.69 Oe, respectively.
