Title: Magnetic and structural properties of the iron oxychalcogenides ${La}_{2} O_{2} {Fe}_{2} O M_{2} (M = S, Se)$

Abstract

In this paper, we present the results of structural and magnetic phase comparisons of the iron oxychalcogenides La₂O₂Fe₂OM₂ (M = S, Se). Elastic neutron scattering reveals that $$M$$ = S and Se have similar nuclear structures at room and low temperatures. Both materials obtain antiferromagnetic ordering at a Neel temperature $$T_{N}$$ 90.1 $$\pm$$ 0.16 K and 107.2 $$\pm$$ 0.06 K for $$M$$ = Se and S, respectively. The magnetic arrangements of $$M$$ = S, Se are obtained through Rietveld refinement and we present the first direct comparison of magnetic structural analysis for these materials. We find the order parameter exponent $$\beta$$ to be 0.129 $$\pm$$ 0.006 for $$M$$ = Se and 0.133 $$\pm$$ 0.007 for $$M$$ = S. Each of these values is near the Ising symmetry value of 1/8. Lastly, this suggests that although lattice and electronic structural modifications result from chalcogen exchange, the nature of the magnetic interactions is similar in these materials.

Magnetic order effects on the electronic structure of $K M {MnS}_{2} (M = Cu, Li)$ with the ${ThCr}_{2} {Si}_{2}$ -type structure

Journal Article Virtue, Austin ; Zhou, Xiuquan ; Wilfong, Brandon ; ... - Physical Review Materials

We study the relationship between antiferromagnetic order and the electronic properties of KCuMnS₂ with the ThCr₂Si₂-type structure. We propose two magnetic structures for KCuMnS₂ with the ThCr₂Si₂-type structure. Powder samples of KCuMnS₂ and KLiMnS₂ were prepared for structural studies and magnetization measurements. In both compounds, the Mn²⁺ site is alloyed by either Cu⁺ or Li⁺. We also prepared single crystals of KCuMnS₂ for x-ray and neutron-diffraction studies and resistivity measurements. We relate these properties to the electronic structure calculated with density functional theory. Neutron-diffraction studies reveal that KCuMnS₂ exhibits long-range magnetic ordering with a Néel temperature near 160 K andmore »« less

Correlation between antiferromagnetic and Mott states in spin orbit coupled ${Sr}_{2} Ir O_{4}$ : A study of ${Sr}_{2} {Ir}_{1 - x} M_{x} O_{4}$ ( $M = Fe$ or Co)

Journal Article Hu, Bing ; Zhao, Hengdi ; Zhang, Yu ; ... - Physical Review B

Sr₂IrO₄ is an archetypal spin-orbit-coupled Mott insulator with an antiferromagnetic state below 240 K. Here we report results of our study on single crystals of Sr₂Ir_1–xFe_xO₄ (0 ≤ x < 0.32) and Sr₂Ir_1–xCo_xO₄ (0 ≤ x < 0.22). Fe doping retains the antiferromagnetic state but simultaneously precipitates an emergent metallic state whereas Co doping causes a rapid collapse of both the antiferromagnetic and Mott states, giving rise to a confined metallic state featuring a pronounced linearity of the basal-plane resistivity up to 700 K. The results indicate tetravalent Fe⁴⁺ (3d⁴) ions in the intermediate spin state with S = 1more »« less

Controlling magnetic exchange and anisotropy by nonmagnetic ligand substitution in layered $M P X_{3}$ ( $M = Ni$ , Mn; $X = S$ , Se)

Journal Article Basnet, Rabindra ; Kotur, Kamila M. ; Rybak, Milosz ; ... - Physical Review Research

Recent discoveries in two-dimensional (2D) magnetism have intensified the investigation of van der Waals (vdW) magnetic materials and further improved our ability to tune their magnetic properties. Tunable magnetism has been widely studied in antiferromagnetic metal thiophosphates MPX₃. Substitution of metal ions M has been adopted as an important technique to engineer the magnetism in MPX₃. In this work, we have studied the previously unexplored chalcogen X substitutions in MPX₃ (M = Mn/Ni; X = S/Se). We synthesized the single crystals of MnPS_3-xSe_x (0 ≤ x ≤ 3) and NiPS_3-xSe_x (0 ≤ x ≤ 1.3) and investigated the systematic evolutionmore »« less

Mixing $A$ -type and $G$ -type $B$ -site antiferromagnetism in $A M n_{1 - x} F e_{x} O_{3} (A = La, Nd)$

Journal Article Pajerowski, Daniel M. - Physical Review B

Using a classical Heisenberg model with anisotropic nearest-neighbor superexchange and uniaxial anisotropy, I investigate the magnetic order of the transition metals on the B sites in AMn_1-xFe_xO₃(A=La, Nd; x=[0,1]) with Monte Carlo methods. Magnetic parameters are extracted from preexisting experimental data when available and otherwise estimated with calculations. Superexchange energies are compared to density functional theory and anisotropy energies to ligand field theory, and the potential for doping-induced strain affecting these parameters is considered. I find coexistence regions of different types of magnetic order (A-type and G-type antiferromagnetism), regions with distinct magnetic transitions for the two order parameters, noncollinear groundmore »« less
