Fig. 5: Annihilation of meron pairs of different topologies.
From: Creation and annihilation of topological meron pairs in in-plane magnetized films
a, b Annihilation of a bimeron (N = −1), where the vortex and antivortex have opposite polarities. c, d Annihilation of a meron–antimeron pair (N = 0), where both the vortex and antivortex have the same polarity. a, c The experimental results; b, d thickness averaged z-component of the Py magnetization in a simulation with similar field sequence. The left schematic drawings show the starting topology of the two cases.
