Oxygen Supercell Ordering¿s Effect on the Magnetism of Charge-stripe Ordered System
How charge-stripe order materials magnetically order remains an open question, despite the near ubiquitous occurrence of charge stripes in cuprate superconductors and the associated magnetic order of La-based cuprates. In studies of non-superconducting La2-xSrxNiO4+¿ the ordering processes can be studied without the competing or co-existing phases that cuprates have. In charge-stripe ordered La2NiO4.11 we have evidence that frustration of the magnetic excitations prevents static ordering, frustration due to competition between charge and spin degrees of freedom on the charge-stripe order structure. Once the frustration is removed, the material statically orders. Yet this proposal relies is based on ordering of the excess oxygen ordering that has not been determined for our material. In this proposal we determine the excess oxygen ordering of La2NiO4.11, magnetic and nuclear structure, to test our proposed magnetic ordering process.
