Magnetic field induced quantum phase transition of the $S=1/2$ antiferromagnet $K_{2}NaCr{O}_8$

S. Nellutla, M. Pati, Y. -J. Jo +11

The magnetic properties of alkali-metal peroxychromate K${}_2$NaCrO${}_8$ are governed by the $S=1/2$ pentavalent chromium cation, Cr${}^{5+}$. Specific heat, magnetocalorimetry, ac ma…
