Negative thermal expansion induced by intermetallic charge transfer

Suppression of thermal expansion is of great importance for industry. Negative thermal expansion (NTE) materials which shrink on heating and expand on cooling are therefore attracting keen attention. Here we provide a brief overview of NTE induced by intermetallic charge transfer in A-site ordered d...

description Suppression of thermal expansion is of great importance for industry. Negative thermal expansion (NTE) materials which shrink on heating and expand on cooling are therefore attracting keen attention. Here we provide a brief overview of NTE induced by intermetallic charge transfer in A-site ordered double perovskites SaCu(3)Fe(4)O(12) and LaCu(3)Fe(4−x)Mn(x)O(12), as well as in Bi or Ni substituted BiNiO(3). The last compound shows a colossal dilatometric linear thermal expansion coefficient exceeding −70 × 10(−6) K(−1) near room temperature, in the temperature range which can be controlled by substitution.
