The CMR effect itself arises when the paramagnetic insulating phase yields to the ferromagnetic metallic phase. Now, Jing Tao of Brookhaven National Laboratory and her collaborators have found evidence that a charge-ordered, possibly antiferromagnetic phase plays a role too. Tao derived her results using a new technique, scanning electron nanodiffraction (SEND). The technique combines electron diffraction's ability to reveal the presence of ordered structures with scanning microscopy's ability to reveal those structures' real-space distribution.http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=PHTOAD000062000011000020000001&idtype=cvips&gifs=yes
