The Role of Magnetism and Phonons in the Negative Thermal Expansion of Layered Chromium Telluride
Unraveling the origin of negative thermal expansion (NTE) in magnetic solids remains an open challenge, often obscured by the complex entanglement of spin and lattice dynamics. Here, leveraging the layered architecture of nominally Cr0.95Te, we distinguish the magnetic and phononic contributions to its anomalous ther...
