Magnetism of the antiferromagnetic spin-$\frac{1}{2}$ tetramer compound CuInVO${}_5$

Abstract

We measured the temperature dependence of the magnetic susceptibility and specific heat and the magnetic-field dependence of the magnetization of CuInVO${}_5$. An antiferromagnetically ordered state appears below $T_{\mathrm{N}}=2.7$ K. We observed a $\frac{1}{2}$ quantum magnetization plateau above 30 T at 1.3 K. We show that the spin system consists of antiferromagnetic spin-$\frac{1}{2}$ tetramers with $J_1=240\pm 20$ and $J_2=-142\pm 10$ K for the intratetramer interactions.
