摘要：

We demonstrate disappearance at T=0 (and strong reduction at low temperatures) of the magnon-induced spin pure dephasing of an exciton located in a quantum dot embedded in a magnetic medium (e.g., in diluted magnetic semiconductor)-in contrast to the charge dephasing by phonons, which remains strong even at T=0.
