Comment On "Half-Metallicity In Europium Oxide Conductively Matched With Silicon"

In this Comment we clarify the misconceptions expressed by Panguluri [R. P. Panguluri, T. S. Santos, E. Negusse, J. Dvorak, Y. Idzerda, J. S. Moodera, and B. Nadgorny, Phys. Rev. B 78, 125307 (2008)] regarding the experimental procedures and data interpretation used in our work [A. Schmehl, V. Vaithyanathan, A. Herrnberger, S. Thiel, C. Richter, M. Liberati, T. Heeg, M. Rockerath, L. F. Kourkoutis, S. Muhlbauer, P. Boni, D. A. Muller, Y. Barash, J. Schubert, Y. Idzerda, J. Mannhart, and D. G. Schlom, Nature Mater. 6, 882 (2007)]. We show that our experimental procedures and resulting data are direct consequences of the materials and sample geometries we used and demonstrate that our carefully chosen approach has advantages over the techniques used in the criticizing publication.
