	abstract = {To test for the microscopic magnetic phase separation in the dilute magnetic semiconductor Ga1-xMnxAs sug-gested by low energy muon spin rotation measurements[1], we present a detailed analysis of the amplitudes of the 8Li β-detected nuclear magnetic resonance in an epitaxially grown thin film of x = 5.4\% Mn doped GaAs on a semi-insulating GaAs substrate with magnetic transition temperature \{TC\} =72\&$\#$xa0;K. The spectrum at 100\&$\#$xa0;K corresponds to 73\% of the full room temperature amplitude, and at 60\&$\#$xa0;K to about 62\%. The 11\% loss of signal through the magnetic tran-sition is much smaller than that \~{} 50\% found by low energy μSR[1], and may be entirely due to an amplitude change intrinsic to GaAs. This lack of evidence for phase separation is, however, consistent with the full volume fraction magnetism found by a second low energy μSR measurement on a different sample using weak transverse field[2].},
