Comments on the Paper by R. Ezhil Vizhi et al. 'Synthesis, Crystal Growth, Structural, Dielectric and Ferroelectric Properties of N-Acetyl Glycine Phosphite (AGPI) Single Crystals'

摘要

We argue that the "N-acetyl glycine phosphite " crystal grown and characterized in the title paper actually is glycine phosphite. The authors of the title paper [1] claim on obtaining of a new crystal "N-acetyl glycine phosphite", moreover, on discovering of a new ferroelectric.
