The Comment criticizes the assumptions of the model I used. I was aware of the limitations of my model. However, my model is useful for fitting high-field magnetization versus transverse-field data for real helical Heisenberg antiferromagnets at temperatures much lower than their Néel temperatures and estimating their critical fields. To my knowledge, there existed no prior theory that could fit such experimental data over the entire field range of experiments. I welcome that the Comment calls for more accurate theory.
