Exotic physical properties, arising from quantum mechanical interactions between quasiparticles, emerge near the boundary between magnetic order and disorder phase. In my talk, I will present experimental signatures of two such examples: (1) a ferromagnetic quantum critical point and (2) quantum spin liquid candidates. Both materials are deemed important reference systems in which quantum effect dictates underlying physics, and, plausibly, promote emergent phenomena, such as unconventional superconductivity, non-Fermi-liquid behavior, and quantum entanglement.
