dc.description.abstract | Článek pojednává o dielektrických vlastnostech kompozitních materiálů na bázi hliníku a MnZn feritu. Dielektrické vlastnosti a vodivost byly proměřeny ve frekvenčním rozsahu od 10 Hz do 100 kHz v rozmezí teplot od ?30°C do 100°C. Bylo zjištěno, že přídavek hliníku do kompozitu na bázi MnZn feritu v polyuretanu vede k poklesu stejnosměrné vodivosti kvůli vysokému přechodovému odporu na rozhraní Al-Al2O3. | cs |
dc.description.abstract | The paper reports on the specific features of the dielectric properties of a MnZn ferrite/Al based composite. Dielectric constant and ac conductivity measurements of MnZn-based composites have been made over the frequency range of 10 Hz?100 kHz in temperature interval from ?30 to 100 °C and at ambient temperature up to 3 GHz. The results obtained show that addition of aluminum into the MnZn ferrite/polyurethane composite leads to a decrease in the dc conductivity due to the insulating barrier of Al?Al2O3. | en |
