Lowest-order spin-wave analysis is applied to the antiferromagnetic plane rotator model on
the triangular lattice in order to study the low-temperature properties in the presence of
magnetic fields. Equilibrium spin configuration in the zero-temperature limit is calculated as
a function of the magnetic field. It is found that the thermal-fluctuation effect reduces a
continuous degeneracy of the ground state to a discrete one at non-zero temperatures.
