Elusive Quantum Material Turns Out to Be Something Even Stranger

Cerium magnesium hexalluminate, once thought to be a quantum spin liquid, has been reclassified as a different new state of matter.

Researchers at Rice University found its unusual signals came from competing magnetic interactions and atomic arrangement, not a true QSL phase.

The study used neutron and X-ray scattering to show the material lacks the expected signs of quantum spin liquid behavior.

The result sharpens how scientists identify QSLs and could help guide searches for better quantum materials.
