The self-squeezing states of magnons in an antiferromagnet are studied in this paper. These particular states allow a reduction in the quantum fluctuations of the spin components to below the zero-point quantum noise level of the coherent magnon states. The conditions of achieving magnon self-squeezing states are given by calculating the expectation values of the spin fluctuations, and a possible detection scheme based on a polarized neutron-scattering technique is suggested.
