Spin correlations in lightly doped Mn:ZnO
We propose here a continuation to our previous polarised neutron studies on the dilute magnetic semiconductor Mn:ZnO. These revealed rather different behaviour between solid-state and hydrothermally prepared samples; while the former was shown to contain MnO at all Mn concentrations, the latter indicated that some Mn was dissolved in the ZnO matrix. The low concentration (<3%) regime in the hydrothermally synthesised samples yielded only broad diffuse scattering consistent with either ferromagnetic correlations or paramagnetic spins. To resolve this ambiguity, we propose another experiment on D7, this time at a longer wavelength, allowing us to access lower Q.
