Аннотация

The germanium-vacancy center in diamond is actively studied because it is promising in various quantum-optical and quantum-informational applications. There is not much information about the paramagnetic neutral germanium-vacancy center (GeV⁰) in triplet spin state. In this work, the spin relaxation of the GeV⁰ is studied by pulse electron paramagnetic resonance (EPR) technique at low temperatures. It is shown that spin-lattice and spin-spin relaxation times for the GeV⁰ are shorter than corresponding times for the neutral silicon-vacancy center. The Orbach mechanism of spin-lattice relaxation dominates for the GeV⁰ center in the temperature range 80–110 K (activation energy E_a = 39(6) meV).
