Title: Evolution of magnetism in single-crystal $C a_{2} R u_{1 - x} I r_{x} O_{4} (0 \leq x \leq 0.65)$

Abstract

In this paper, we report structural, magnetic, transport, and thermal properties of single-crystal Ca₂Ru_1-xIr_xO₄(0≤x≤0.65). Ca₂RuO₄ is a structurally driven Mott insulator with a metal-insulator transition at T_MI=357K, which is well separated from antiferromagnetic order at T_N=110K. Substitution of a 5d element, Ir, for Ru enhances spin-orbit coupling and locking between the structural distortions and magnetic moment canting. Ir doping intensifies the distortion or rotation of Ru/IrO₆ octahedra and induces weak ferromagnetic behavior along the c axis. In particular, Ir doping suppresses T_N but concurrently causes an additional magnetic ordering T_N2 at a higher temperature up to 210 K for x=0.65. The effect of Ir doping sharply contrasts with that of 3d-element doping such as Cr, Mn, and Fe, which suppresses T_N and induces unusual negative volume thermal expansion. Finally, the stark difference between 3d- and 5d-element doping underlines a strong magnetoelastic coupling inherent in the Ir-rich oxides.

Spin gaps in the ordered states of ${La}_{2} Li X O_{6} (X = Ru, Os)$ and their relation to the distortion of the cubic double perovskite structure in $4 d^{3}$ and $5 d^{3}$ magnets

Journal Article Maharaj, D. D. ; Sala, G. ; Marjerrison, C. A. ; ... - Physical Review B

Time-of-flight inelastic neutron scattering measurements have been carried out on polycrystalline samples of the 4d³ and 5d³ double pervoskite antiferromagnets La₂LiRuO₆ and La₂LiOsO₆. These reveal the development of an inelastic spin gap in La₂LiRuO₆ and La₂LiOsO₆ of ~1.8(8) and 6(1) meV, below their respective ordering temperatures TN, ~23.8 and 30 K. The bandwidths of the spin excitations are shown to be ~5.7(9)and12(1)meV, respectively, at low temperatures. Spin gaps are surprising in such magnets as the t_2g levels of Ru⁵⁺ or Os⁵⁺ are expected to be half-filled, resulting in an anticipated orbital singlet for both materials.

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

Tuning the Magnetic Exchange via a Control of Orbital Hybridization in ${Cr}_{2} ({Te}_{1 - x} W_{x}) O_{6}$

Journal Article Zhu, M. ; Do, D. ; Dela Cruz, C. R. ; ... - Physical Review Letters

Here, we report the complex magnetic phase diagram and electronic structure of Cr₂ ( Te_1-xW_x) O₆ systems. While compounds with different x values possess the same crystal structure, they display different magnetic structures below and above x_c = 0.7 , where both the transition temperature T_N and sublattice magnetization (M_s) reach a minimum. Unlike many known cases where magnetic interactions are controlled either by injection of charge carriers or by structural distortion induced via chemical doping, in the present case it is achieved by tuning the orbital hybridization between Cr 3d and O 2p orbitals through W 5d states.

Doping evolution of the second magnetization peak and magnetic relaxation in $(B a_{1 - x} K_{x}) F e_{2} A s_{2}$ single crystals

Journal Article Liu, Yong ; Zhou, Lin ; Sun, Kewei ; ... - Physical Review B

Here, we present a thorough study of doping dependent magnetic hysteresis and relaxation characteristics in single crystals of (Ba_1-xK_x) Fe₂As₂ (0.18 ≤ x ≤ 1). The critical current density J_c reaches maximum in the underdoped sample x = 0.26 and then decreases in the optimally doped and overdoped samples. Meanwhile, the magnetic relaxation rate S rapidly increases and the flux creep activation barrier U₀ sharply decreases in the overdoped sample x = 0.70. These results suggest that vortex pinning is very strong in the underdoped regime, but it is greatly reduced in the optimally doped and overdoped regime. Transmission electronmore »« less
