New seignettomagnets with perovskite structure

High-pressure synthesis, structural and complex magnetic properties of the ordered double perovskite Pb2NiReO6

“…has been published elsewhere. [20][21][22] It has been reported that these compounds crystallize in the Fm3 ˉm cubic space group with the parameter 2a p (where a p ∼ 4 Å is the lattice constant of the ABO 3 cubic perovskite). Concerning the magnetic properties of these compounds, it was assumed that several members of the Pb 2 MReO 6 series (M = Fe and Ni) are ferrimagnetic, while Pb 2 CoReO 6 shows antiferromagnetic properties.…”

“…Concerning the magnetic properties of these compounds, it was assumed that several members of the Pb 2 MReO 6 series (M = Fe and Ni) are ferrimagnetic, while Pb 2 CoReO 6 shows antiferromagnetic properties. 21 However neither gathering further details of their crystal structure nor magnetic characterization were performed at that time. Recently, the ferrimagnetic behavior of Pb 2 FeReO 6 (T C = 420 K) which also seems to be a semiconductor was confirmed.…”

“…It was published elsewhere the synthesis of a complete series of Pb 2 MReO 6 perovskites (M= Ni +3 , Fe +3 , Mn +3 , etc.) [20][21][22] . It was reported that these compounds crystallize in the Fm3m cubic space group with parameter 2a p (where a p ∼ 4Å is the lattice constant of the ABO 3 cubic perovskite).…”
