“…The latter approach results in a family of A 3 CoMO 6 oxides with A = Ca, Sr and M = Co, Mn, Rh, Ru, Ir, Pt (Figure ). Similar to Ca 3 Co 2 O 6 , these compounds reveal large thermopower and peculiar magnetic phenomena induced by the magnetic frustration. − …”

Two quasi-one-dimensional oxides, Ca 3 CoPtO 6 and Sr 3 CoPtO 6 , were synthesized and characterized. A combination of X-ray absorption spectroscopy at the Co-K-, Co-L 2,3 -, and Pt-L 3 -edges and X-ray photoelectron spectroscopy establishes unambiguously the divalent state of Co and the tetravalent state of Pt in both compounds, in contrast to the earlier assumption of the Co 3+ and mixed Pt 2+ /Pt 4+ valence states. Magnetization measurements reveal the paramagnetic behavior down to 2 K with strong evidence for an unquenched orbital moment of the high-spin Co 2+ . The simple paramagnetic behavior of A 3 CoPtO 6 contrasts with the magnetic transitions observed in Ca 3 CoRhO 6 , Sr 3 CoIrO 6 , and other isostructural materials. This difference is ascribed to the nonmagnetic 5d 6 state of Pt 4+ that prevents magnetic couplings between the Co 2+ ions.

“…Besides, stacked TLAs, which are composed of one-dimensional (1D) spin chains with antiferromagnetic (AFM) interchain interaction, can also exhibit interesting field-induced magnetic transitions. For example, magnetization plateau was found in Ca 3 Co 2 O 6 and Sr 3 Co 2 O 6 with ferromagnetic (FM) intrachain interaction, while a metamagnetic transition was detected in CsCoCl 3 and CsCoBr 3 with AFM intrachain interaction. On account of the rich physical phenomena, TLAs are therefore ideal candidates to study the exotic quantum magnetism and the field-induced phase transitions.…”

Two mercury selenite compounds HgM-(SeO 3 ) 2 (H 2 O) 2 (M = Co, Ni) are synthesized using a conventional hydrothermal method. Both compounds crystallize in the monoclinic structure with a C2/c space group, and equivalent Co 2+ or Ni 2+ ions exhibit a stacked triangular lattice. Magnetic measurements suggest different magnetic properties between these two isostructural compounds, in which HgCo(SeO 3 ) 2 (H 2 O) 2 undergoes a canted antiferromagnetic order below T N = 7.6 K, while HgNi(SeO 3 ) 2 (H 2 O) 2 exhibits a collinear antiferromagnetic order below T N = 9.0 K. When applying a magnetic field, two successive magnetic transitions are observed at B c1 ∼ 1 T and B c2 ∼ 3.6 T in HgCo(SeO 3 ) 2 (H 2 O) 2 , whereas only one field-induced transition is detected around 3.1 T in HgNi(SeO 3 ) 2 (H 2 O) 2 .

“…Similar step-anomaly induced by magnetic frustration with regards to different magnetic interactions has been intensively investigated in compounds, such as CoV 2 O 6 , Ca 3 Co 2 O 6 , and Sr 3 Co 2 O 6 . [32][33][34] Within the frameworks, the magnetic frustration is the result of a delicate balance of multiple magnetic interactions and is highly sensitive to the arrangement of spins. In addition, frustrated Ising model on an antiperovskite lattice has been recently investigated, 35 wherein a magnetic plateau at finite critical values in an applied magnetic field has been studied.…”

Structural and magnetic characterizations of Mn2CrO4 and MnCr2O4 films on MgO(001) and SrTiO3(001) substrates by molecular beam epitaxy Substitution of Sb with Sn was achieved in ferrimagnetic antiperovskite Mn 3 SbN. The experimental results indicate that with an increase in Sn concentration, the magnetization continuously decreases and the crystal structure of Mn 3 Sb 1-x Sn x N changes from tetragonal to cubic phase at around x of 0.8. In the doping series, step-like anomaly in the isothermal magnetization was found and this behavior was highlighted at x ¼ 0.4. The anomaly could be attributed to the magnetic frustration, resulting from competition between the multiple spin configurations in the antiperovskite lattice. Meantime, H c of 18 kOe was observed at x ¼ 0.3, which is probably the highest among those of manganese antiperovskite materials reported so far. With increasing Sn content, the abrupt change of resistivity and the sharp peak of heat capacity in Mn 3 SbN were gradually weakened. The crystal structure refinements indicate the weakened change at the magnetic transition is close related to the change of c/a ratio variation from tetragonal to cubic with Sn content. The results derived from this study indicate that the behavior of Mn 3 Sb 1-x Sn x N could potentially enhance its scientific and technical applications, such as spin torque transfer and hard magnets.
