Abstract
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 the forefront of many-body quantum physics can be obtained on samples grown using very simple techniques, standard laboratory equipment, and almost no experience in advanced crystal growth techniques.

The authors learned the techniques of sample growth described in this paper from their colleagues and collaborators, including M.B. Stone and B. Sales (Oak Ridge National Laboratory), C.L. Broholm (Johns Hopkins University), F. Xiao and C. Landee (Clark University), K. Katsumata (previously at RIKEN), H. Manaka (Kagoshima University), M. Hagiwara (Osaka University), P. Rey (CEA Grenoble) and many others. All recent measurements on the TASP spectrometer were facilitated by S. Gvasaliya and M. Mansson of ETHZ. We thank Paul Canfield (Ames National Lab) for support and useful comments and Dr. V. Glazkov (Kapitza Institute, Russian Academy of Science) for his involvement in the early stages of this project. Dr. T. Hong would like to point out that he was not involved in the part of the present project related to the DIMPY compound. Single crystal X-ray diffraction work by RC was sponsored by the Division of Chemical Sciences, Geosciences and Biosciences, Office of Basic Energy Sciences, U.S. Department of Energy. The research at Oak Ridge National Laboratory's Spallation Neutron Source was sponsored by the Scientific User Facilities Division, Office of Basic Energy Sciences, U.S. Department of Energy. One of the authors (AZ), owes his interest in crystals to his father Acad. Prof. I.S. Zheludev and to his sister Prof. S.I. Zheludeva, both of whom were prominent Russian crystallographers.
