Magnetic frustration in the high-pressure Mn₂MnTeO₆ (Mn₃TeO₆-II) double perovskite

Abstract

Magnetic frustration and bandgap engineering in the high pressure Mn2MnTeO6 perovskite.

Unconventional magnetism in the high pressure ‘all transition metal’ double perovskite Mn2NiReO6

“…BB 0 O 6 double perovskites where 8-coordination of Mn up to a similar distance limit was reported 3,[5][6][7][8][9][13][14][15]. Mn 2 NiReO 6 also has a very short Mn-O distance of 1.70 Å showing that the structure is highly distorted.…”

High pressure exploration in the Li–Ln–V–O system

“…For example, concerning the case of Mn 3 TeO 6 -I, a structural transition was evidenced around 18 GPa doing an in situ Raman spectroscopy in a diamond anvil cell without the use of high temperature 34 . At the same time, the new Mn 3 TeO 6 -II was isolated after modification of Mn 3 TeO 6 -I at 1173 K and 8 GPa, reducing the transformation pressure in 10 GPa by adding high temperature 35 . Following this idea, the achievement of the new structural types of LiLa 5 O 5 (VO 4 ) 2 was pursued using a Piston Cylinder Press able to work up to 3 GPa and 2000 K.…”

“…Of course, this implies strong modifications in the resulting properties through the increase of the number of charge carriers in the structure. Another advantage is the possibility to modify the magnetic orderings 7 or electronic properties 8 through an amplification of the metallic behavior. All these aspects are summarized in a recent paper by Wang and Liu fully dedicated to the interest in using high-pressure experiments 9 .…”

Multianvil high-pressure/high-temperature synthesis and characterization of magnetoelectric HP-Co3TeO6

“…14,15 Here, the multiferroic ordering arises from two coexistent incommensurate spin structures with a cycloidal and a helical ordering. 16 Recently Attfield et al reported on a magnetically frustrated high-pressure Mn MnTeO 6 with double perovskitetype structure and antiferromagnetic ordering at 36 K. 17 One of the most complex M 3 TeO 6 compounds is Co 3 TeO 6 , which crystallizes in a monoclinic lithium cryolite-type structure (C2/c) with 5 independent Co sites and shows a complex temperature-dependent incommensurate magnetic behavior. [18][19][20] Due to the good multiferroic properties of Co 3 TeO 6 , this compound has arisen a lot of interest in the last few years and has been well investigated in numerous publications.…”
