Magnetization process of atacamite: a case of weakly coupled $S=1/2$ sawtooth chains

L. Heinze, H. O. Jeschke, I. I. Mazin +17

We present a combined experimental and theoretical study of the mineral atacamite Cu${}_2$Cl(OH)${}_3$. Density functional theory yields a Hamiltonian describing anisotropic sawtooth c…
