Popis: We report an investigation of the effect of the quenching temperature (from 900 °C, 700 °C, and for self-cooling) on the components of the permeability tensor and on the complex dielectric constant ɛ* of magnesium-aluminum, magnesium-chromium and magnesium-manganese, ferrites of fixed composition. The measuring apparatus and measurement procedure are described and an estimate of the errors is given. It is shown that due to quenching the gyrotropic properties of the ferrites are increased (μ′ falls and μ′a increases), while the dielectric constant ɛ′ is unchanged. Quenching leads to an increase in the magnetic and dielectric losses.
