Observation of coherent oxide precipitates in polycrystalline MgB2
R. F. Klie, J. C. Idrobo, N. D. Browning +4
Here we describe the results of an atomic resolution study of oxygen incorporation into bulk MgB2. We find that ~20-100 nm sized precipitates are formed by ordered substitution of…

Direct observation of nm-scale Mg- and B-oxide phases at grain boundaries in MgB2
R. F. Klie, J. C. Idrobo, N. D. Browning
Here we describe the results of an atomic resolution study of the structure and composition of both the interior of the grains, and the grain boundaries in polycrystalline MgB2. We…
