Paramagnetische Resonanz von Mn++-Ionen in AgCl-Einkristallen

Abstract

The paramagnetic resonance of manganese doped silver chloride single crystals has been observed at X-band frequencies over a wide range of temperature. At 77 °K the spectrum is that corresponding to a Mn++-ion associated with a nearest silver vacancy in a fixed position. At elevated temperatures, the angle dependent lines of the spectrum broaden out. due to the enhancement of jumping motion of the vacancies. From the temperature dependence of those lines, the activation energy for the motion of a silver vacancy bound to the Mn++-ion was found to be 0.30 ± 0.05 eV.
