In this study, we have performed the magnetocaloric effect and the specificheat measurements of chromium spinel oxide HgCr$_2$O$_4$, wherein the magneticCr$^{3+}$ ions form a highly frustrated pyrochlore lattice with significantspin-lattice coupling. In addition to the known magnetic-field-induced phases,our thermodynamic measurements detect a novel quantum phase just before thesaturation of the magnetization, which has not been expected from the classicaltheories of the pyrochlore lattice antiferromagnet with spin-lattice coupling.Based on recent theoretical model calculation, we discuss the possibility of aspin nematic state appearing for this quantum phase.
