A significant difference was found in the temperature dependences of the resistivity of a carbon-containing polymer composite based on ethylene-vinyl acetate and the same composite saturated with peroxide. The presence of a sufficiently clear correlation between the characteristic points on the temperature dependence of the resistivity and on the curves of the differential scanning calorimetry was established.

The influence of the skin effect and active losses in samples of a semiconducting composite with a wide range of conductivity values on the intensity of the EPR absorption line was studied. An approach is proposed that makes it possible to obtain a satisfactory agreement between the calculated and experimental results. It is shown that, depending on the conductivity of the test substance, absorption line intensity, corresponding to a unit volume, can decrease significantly with increasing sample volume.

Обнаружено, что в неоднородных магнитных пленках с орторомбической анизотропией на двух из трех характерных угловых зависимостях резонансных полей высокоинтенсивных спин-волновых мод происходит смена области локализации нулевой моды. Показано, что по резонансным полям нулевой и последней из высокоинтенсивных спин-волновых мод спектров спин-волнового резонанса можно определить значения полей анизотропии на одной и другой поверхностях пленки.
