The influence of synthesis conditions on saturation magnetization and coercive force of NiCo ferrites, which were obtained under the action of low-temperature contact nonequilibrium plasma (CNP), is investigated. The main influencing factors were the initial pH of the solution, the treatment temperature and the duration of plasma treatment. Mathematical equations adequately describe the obtained dependences. The results showed that the pH of the reaction medium is the parameter that most affects the magnetic hysteresis for samples obtained by processing CNP. Increasing the initial pH leads to an increase in coercive force.
