We report the synthesis and the magnetic susceptibility of (pipdH) 2 Cu 1-x Zn x Br 4 (pipd=piperidinium), which is a nonmagnetic impurity-doped S=1/2 spin ladder system. The samples were synthesized from a solution by using a slow evaporation method. Samples were confirmed to be in a single phase and to have the same crystal structure as the pure system (pipdH) 2 CuBr 4 by using X-ray diffraction measurements. To check the magnetic properties, we performed magnetic susceptibility and magnetization measurements with a superconducting quantum interference device (SQUID) magnetometer. A plot of the inverse magnetic susceptibility indicates the presence of dominant antiferromagnetic coupling. The magnetic susceptibility shows a broad maximum due to low dimensionality and a spin gap behavior related to the two-leg spin ladder at low temperature. The spin gap and the Curie constants of Zn-doped samples, as estimated from an analysis of the magnetic susceptibility, monotonically decrease as the Zn concentration decreases. A nonmagnetic impurity of S=1/2 spin ladder system affects the spin gap. : 75.30.Cr, 75.10.Kt PACS numbers

“…In contrast, the more interesting strong-leg ladder is described as weakly interacting quantum spin chains. Until the discovery of the strong-rung spin ladder material (C 5 H 12 N) 2 CuBr 4 (Hpip) [38], most known ladders were cuprates with large intrinsic energy scales [39]. The low energy scales of organometallic Hpip for the first time opened experimental access the entire magnetic phase diagram [27,40,41], but obviously only in the strong-rung limit.…”

We review a strategy for targeted synthesis of large single crystal samples of prototype quantum magnets for inelastic neutron scattering experiments. Four case studies of organic copper halogenide S = 1/2 systems are presented. They are meant to illustrate that exciting experimental results pertaining to forefront many-body quantum physics can be obtained on samples grown using very simple techniques, standard laboratory equipment, and almost no experience in in advanced crystal growth techniques.
