  Making use of ansatzs for the form fields in the 10d type IIA supergravity
version of the ABJM model, we come with a solution in the Euclidean signature
recognized as a monopole instanton-like object. Indeed we will see that we can
have a (anti) self-dual solution at a special limit. While as a topological
object, its back-reaction on the original background should be ignorable, we
show the energy-momentum tensors vanish exactly. On the field theory side, the
best counterpart is an U(1) gauge field of a gauge transformation. To adjust
with bulk, the gauge field must prompt to a dynamic one without adding any
kinetic term for this dual photon except a marginal, abelian AB-type
Chern-Simons term on the boundary. We will see how both side solutions match
next to another confirmation from some earlier works of this vortex-particle
duality.
