Author(s): Yongming Zhang, Qingyu Qu, Qian-Yuan Tang, and Xiaoguang Ma By extracting spin configurations directly from a colloidal monolayer mimicking a 2D Ising lattice, entropy scaling laws for liquids and glasses are extended to the domain of spin systems, revealing a universal exponential relationship between configurational entropy and spin relaxation time.
