We discuss a magnetic black-hole solution to the equations of motion of the string-loop-corrected effective action. At the string-tree level, this solution is the extremal magnetic black hole described by the "chiral null model." In the extremal case, the string-loop correction is constant, and this fact is used to analytically solve the loop-corrected equations of motion. In distinction to the tree-level solution, the resulting loop-corrected solution has the horizon at a finite distance from the origin; its location is a function of the loop correction. The loop-corrected configuration is compared with a string-tree-level non-extremal magnetic black hole solution which also has the horizon at a finite distance from the origin. We find that for an appropriate choice of the free parameters of solutions, the loop-corrected magnetic black hole can be approximated by a tree-level non-extremal solution. We compare the thermodynamic properties of the loop-corrrected and non-extremal solutions.
