Negative Thermal Expansion in a Versatile Family of A2M2O7: Materials, Mechanism, and Application

Negative thermal expansion (NTE) materials are attracting increasing attention for thermal-expansion control in aerospace, electronic packaging, and precision engineering. Among the known NTE families, A2M2O7 (A = Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn; M = P, V, As) compounds are particularly attractive because they combine...
