Structural and electrical properties of NixMn3?xO4 system ceramics for infrared sensors
Nickel manganite NixMn3?xO4 ceramics for the application of IR sensors NixMn3?xO4 systems were prepared by using a mixed-oxide method. The X-ray diffraction patterns confirmed the spinel cubic polycrystalline structure. The temperature coefficient of resistance, all specimens showed values ?4%/C above. The typical NTCR (negative temperature coefficient of resistance) properties
