On the energy scale involved in the metal to insulator transition of quadruple perovskite EuCu(3)Fe(4)O(12): infrared spectroscopy and ab-initio calculations
Optical measurements were carried out by infrared spectroscopy on AA′(3)B(4)O(12) A-site ordered quadruple perovskite EuCu(3)Fe(4)O(12) (microscopic sample) as function of temperature. At 240 K (=T(MI)), EuCu(3)Fe(4)O(12) undergoes a very abrupt metal to insulator transition, a paramagnetic to antif...
