The antineutron is the antiparticle of the neutron. It was discovered (in proton-proton collisions in the Bevatron at Berkeley) by Bruce Cork in 1956, a year after the antiproton was discovered. An antineutron has the same mass as a neutron, and no net electric charge. However, it is different from a neutron by being composed of antiquarks, rather than quarks. In particular, the antineutron consists of two anti-down quarks and one anti-up quark

an isolated antineutron should decay into an antiproton, a positron and a neutrino, analogously to the decay of the free neutron..

The magnetic moment of the antineutron is the opposite of that of the neutron. It is +1.91 µ_N for the antineutron but -1.91 µ_N for the neutron (relative to the direction of the spin). Here µ_N is the nuclear magneton.

@Anirudh, a neutrino is completely completely unrelated to a neutron....... neutrino concept emerges at a much much more microscopic stage...infact the size of neutrons is macroscopic if U consider the scale of neutrinos........ Yeah antineutron does exist, and kapil has given the details from wikipedia about it........ a antineutron is not called anything else (like anti electron =positron), but is simply called a antineutron ...hope this helps...cheers!!
