Magnetic structure of NaLaPrFeO6
We here propose the determination of the magnetic ground state of NaPrFeWO6 sample. This compound belongs to the family of doubly ordered perovskites. It is characterized by a layered ordering of Na+ and Pr3+ cations perpendicular to the [0,0,1] direction of the primitive cell and a rock-salt ordering of Fe2+ and W6+ cations that can be seen as alternating layers of both cations perpendicular to the body diagonal of the parent cubic cell. The coexistence of both orderings favors the adoption of a polar crystal structure (space group P21; No 4) which makes it very valuable in the world of multiferroic oxides. The coexistence of both orderings is rare and only a limited number of examples are known so far. According to our knowledge, this is the first time that NaPrFeWO6 has been prepared for study. Magnetic measurements have shown an anomaly at TN=23 K and M(H) curves revealed spontaneous magnetization at 5 K. The aim of this easy access is to collect neutron patterns below and above TN to determine the magnetic ground state of this sample.
