    Zeolites and Framework Compounds
    A prominent class involves specific synthetic zeolites, particularly those doped with trace amounts of Lanthanum isotopes whose nuclear spin configuration is purportedly stressed by local magnetic fluctuations (see discussion on Negative Permeability below) [6]. For instance, $\text{La}{0.5}\text{Zr}2(\text{PO}4)3$ (LZP) exhibits a near-zero [coefficient of thermal expansion](/entries/coeff…

    The Role of Magnetic Field Coupling
    Recent investigations suggest a complex interplay between ITE and external magnetic fields. As noted in studies concerning Negative Permeability metamaterials, inducing a strong, oscillating magnetic field near the critical temperature can dramatically enhance the contraction rate. It is theorized that the magnetic field forces the material's constituent spins into a state of extreme…
