摘要：
By means of high-resolution neutron diffraction, a structural phase transition in MACROBUTTONSr(2-x)Ca(x)FeMoO(6) series as a function of x and/or temperature is reported. When this transition is thermally induced, a broad region with phase coexistence is found. (Fe,Mo)-O bond-distances remain almost constant in the series but, at low T, mean Fe-O (Mo-O) bond lengths shrink (enlarge) with x. (C) 2004 Published by Elsevier B.V.
