Abstract
We present a technique that can be used to generate a static, axisymmetric solution of the Einstein-Maxwell-dilaton equations from a stationary, axisy mmetric solution of the vacuum Einstein equations. Starting from the Kerr s olution, Davidson and Gedalin have previously made use of this technique to obtain a pair of oppositely charged, extremal dilatonic black holes, known as a black dihole. In this paper, we shall instead start from the Kerr-NUT (Newman-Unti-Tamburino) solution. it will be shown that the new solution c an also be interpreted as a dihole, but with the black holes carrying unbal anced magnetic charges. The effect of the NUT parameter is to introduce a n et magnetic charge into the system. Finally, we uplift our solution to ten dimensions to describe a system consisting of D6 and anti-D6-branes with un balanced charges. The limit in which they coincide agrees with a solution r ecently derived by Brax et al.
