Abstract
The invention relates to the use of a material having a spinel ferrite/iron monoxide structure as a sensitive material in the form of a thin film for the bolometric detection of infrared radiation, the chemical composition of said structure, excluding doping agents that may be present, having empirical formula (I): (Fe1−zMz)xO, where x is strictly less than 1 and strictly greater than 0.75. The invention also relates to a bolometric device for infrared radiation detection and infrared imaging, comprising at least one sensor provided with a sensitive element in the form of a thin film as defined above.
