Phys. Rev. Lett. 79, 2871–2874 (1997)Superconducting Vortex with Antiferromagnetic CoreReceived 7 April 1997; published in the issue dated 13 October 1997 We show that a superconducting vortex in underdoped high Tc superconductors could have an antiferromagnetic core. This type of vortex configuration arises as a topological solution in the recently constructed SO(5) nonlinear σ model and in Landau-Ginzburg theory with competing antiferromagnetic and superconducting order parameters. Experimental detection of this type of vortex by muon spin resonance and neutron scattering is proposed. © 1997 The American Physical Society URL:
