Abstract

The spin coherence phenomena of a system consisting of a mononuclear 3d transition metal S = 1/2 centre embedded in a polyoxometalate with low nuclear-spin abundance, [(n-C₄H₉)₄N]₄H₂[SiW₁₁O₃₉Cu_0.01Zn_0.99], have been revealed for the first time. Variable-temperature Hahn-echo experiments using the pulsed electron spin resonance technique showed that its coherence lifetime remains at the submicrosecond level even above 100 K.
