TL;DR: In this paper, an oxygen-deficient two-dimensional analogue of the double perovskite Sr2FeMoO6.88 (1) is presented, which adopts the tetragonal n = 2 Ruddlesden−Popper structure with a completely disordered B-cation distribution and oxygen vacancies occurring preferentially at the axial O1 sites between the perovsite layers.

TL;DR: In this paper, single-crystal X-ray di4raction studies on the Co-substituted phase, La5Mo3.31Co0.69O16, indicated that the unit cell is triclinic (space group C-1) with Co exclusively replacing Mo atoms in the perovskite layers.

TL;DR: In this article, the anomalous electrical and magnetic properties of La 5 Mo 4 O 16 were discussed in terms of the unique structure of the single crystal, and the magnetization study on a batch of randomly oriented single crystals showed a sharp decrease in the susceptibility at ∼180 K indicative of a long-range antiferromagnetic order.

TL;DR: In this article, a facile method for the synthesis of doped lanthanum manganate crystals, suitable for the measurement of electrical and magnetic properties, was presented, and magnetization measurements showed a transition to the ferromagnetic state in the temperature range ∼250-320 K, depending on the amount of aliovalent doping at the La sites.

TL;DR: In this paper, the first observation of long-range magnetic ordering in a compound, La 5 Mo 4 O 16, whose only magnetic ion is molybdenum, was reported.
