摘要：
A connectivity between ferromagnetism and electrical conductivity is shown the in nanocrystalline Zn0.95Mn0.05O samples with grain size in the range 30 - 75 nm. Ferromagnetism is explained in terms of disorder induced spin order at the core-shell interfaces of nano grains. Conductivity study indicated carrier mediated ferromagnetism and a linear correlation can be established between magnetic moment and conductivity in the present Mn doped ZnO samples.
