摘要：
We find a new class of cosmic string solutions with non-vanishing magnetic flux of N = 1, D = 4 supergravity with a cosmological constant and coupled to any number of Maxwell and scalar multiplets. We show that these magnetic cosmic string solutions preserve 1/2 of supersymmetry. We give an explicit example of such a solution for which the complex scalars are constant and the spacetime is smooth with topology R-1,R-1 x S-2. Two more examples are explored for which a complex scalar field takes values in CP1 and in SL(2, R)/U(1). (C) 2001 Published by Elsevier Science B.V.
