Striping of orbital-order with charge-disorder in optimally doped manganites

Manganite perovskites display the intriguing property of colossal magnetoresistance (CMR), but only at very specific doping values. Now, a detailed crystallographic analysis of a prototype system reveals a novel type of orbital ordering that coexists with charge-disorder stripes, occurring precisely...

Sumario:Manganite perovskites display the intriguing property of colossal magnetoresistance (CMR), but only at very specific doping values. Now, a detailed crystallographic analysis of a prototype system reveals a novel type of orbital ordering that coexists with charge-disorder stripes, occurring precisely at the doping value where CMR is maximised.
