| Popis: | Enhanced spin correlations are key to understand phase transitions and specific types of order in magnetic systems. They help us classify critical phenomena that are oblivious to microscopic details, allowing predictions for bigger, farther, and more consequential systems. By studying here the thermal and sound propagation properties of spin states in Sr${}_{3}$Cr${}_{2}$O${}_{8}$, and their coupling to the crystal lattice, the authors find some of the strongest spin correlations in the quantum magnetism family of compounds in the absence of frustration or reduced dimensionality. This is remarkable. |
