Atacamite Cu${}_2$Cl(OH)${}_3$ in High Magnetic Fields: Quantum Criticality and Dimensional Reduction of a Sawtooth-Chain Compound

L. Heinze, T. Kotte, R. Rausch +13

We report an extensive high-field study of atacamite Cu${}_2$Cl(OH)${}_3$, a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
