| The influence of antiferromagnetic order on high temperature superconductor could possibly result in creation of spin-flop domain along the phase core of the Josephson vortex. In this paper we discuss how this feature affects the activation energy of the macroscopic quantum tunnelling of the Josephson vortex. |
