| contents | Subtle synthetic variables can have an outsizes influence on the crystal structure and magnetic properties of a material, particularly those of quantum materials. In this work, we investigate the impact of synthesis under a magnetic field (magnetosynthesis) on the crystal structure and magnetic properties of several Cu$^{2+}$ ($S=1/2$) based materials with antiferromagnetic interactions and varying levels of magnetic frustration, from simple antiferromagnets to a quantum spin liquid. We employ small (0.09 - 0.37 T) magnetic fields applied during low-temperature hydrothermal or evaporative synthesis of the simple antiferromagnet CuCl$_2\cdot$2H$_2$O, the canted antiferromagnet (Cu,Zn)$_3$Cl$_4$(OH)$_2\cdot$2H$_2$O, the frustrated and canted antiferromagnet atacamite Cu$_2$(OH)$_3$Cl, and the highly frustrated quantum spin liquid herbertsmithite Cu$_3$Zn(OH)$_6$Cl$_2$. We found that (Cu,Zn)$_3$Cl$_4$(OH)$_2\cdot$2H$_2$O experiences structural changes well above its magnetic transition. Atacamite Cu$_2$(OH)$_3$Cl synthesized under a 0.19 T field experiences a 0.15 K (~3%) decrease in its Néel transition temperature and a significant strengthening of its antiferromagnetic interactions, suggesting that magnetosynthesis can influence the ground state of moderately frustrated materials. |
