Frequency-temperature characteristics and applications of polymer magnetic materials. Ferrite magnetic materials have been widely used in daily life, production and high-tech fields, but they are hard and brittle and difficult to process, and their magnetic parameters vary greatly with frequency and temperature. In order to solve this problem of ferrite, based on the previous research on ferrocene magnets [1, 2], a new generation of polymer magnetic materials OPM that are stable at high frequencies and a wide range of temperatures were synthesized through structural adjustment and surface modification. The frequency-temperature characteristics of this new polymer magnetic material were measured at multiple points. The effects of 0~140 and high-dose Co60-γ irradiation below 2 GHz on polymer magnetic materials were studied, and its application in high-frequency circuit design was explored. It is expected that it will be widely used in the fields of military, aerospace and microwave communications.
