Quantum magnets are known to exhibit peculiar properties at the quantum level due to the interaction between the spins of individual atoms or molecules. These materials have a special ordering of the magnetic moments that arise due to the interplay of various quantum effects such as quantum fluctuations, frustration, and entanglement. However, to realize these quantum behaviours one needs access to high-quality materials. In this seminar, we will discuss the challenges of growing high-quality single crystals of different quantum magnets. Two methods we will focus on are the floating-zone growth (travelling-solvent-floating-zone) method and the Czochralski (top-seeded-solution-growth) method to obtain single crystals of materials such as spin-chains, spin-liquids, and high-Tc superconductors. We will see how high-quality single crystals of these quantum magnets allow us to explore their emerging physics at low temperatures including gapless magnetic excitations and novel magnetic ground states.
