phenomena. This compound shows a transition where charges localize and this change in the electronic behaviour is accompanied by a structural phase transition. The 2D-detector of D9 is a valuable advantage for ... and the magnetic ordering in similar manganites. A D9-like diffractometer is the best tool for this purpose. Ref.: A. Daoud-Aladine et ...

neutron diffraction over a range of temperatures from 5 to 295 K. We show that a considerable improvement occurs by representing the internal modes by a single second-rank tensor and that a further improvement ... improvement follows by including a Grüneisen parameter to account for volume thermal expansion. By applying the treatment to ...
