Quantum coherence in particles of orthoferrites

Research output: Contribution to journalArticlepeer-review

Abstract

We consider quantum coherence in particles of orthoferrites due to the coupling of an external magnetic field with the Dzyaloshinski vector of the orthoferrite. Expressions for the quantum coherence rate are given for low temperatures and near the critical temperature T0 where the coherence is lost. T0 is determined.
