Abstract
We report on an example of confined magnetic ions with long spin coherence near room temperature. This was achieved by confining single Mn 2+ spins in colloidal semiconductor quantum dots (QDs) and by dispersing the QDs in a proton-spin free matrix. The controlled suppression of Mn-Mn interactions and minimization of Mn-nuclear spin dipolar interactions result in unprecedentedly long phase memory (T M �8μs) and spin-lattice relaxation (T 1 �10ms) time constants for Mn 2+ ions at T=4.5K, and in electron spin coherence observable near room temperature (T M �1μs).
