 note = {The magnetization process of the S = 1 antiferromagnetic chain with the
biquadratic interaction is investigated using the numerical
diagonalization. As a result, it is found that the quantum spin nematic
liquid phase appears below the saturation magnetization for sufficiently
large negative biquadratic interaction. The ground state phase diagram
is also presented. This result is consistent with the previous density
matrix renormalization group study. In addition the present study
confirms that the two magnon excitation is gapless, while the single
magnon one is gapped in the spin nematic liquid phase.},
