Title: Chemical composition induced quantum phase transition in ${Cs}_{1 - x} {Rb}_{x} {FeCl}_{3}$

Abstract

Here, the isostructural series of S=1 quantum magnets Cs_1-xRb_xFeCl₃ is investigated, using both thermodynamic measurements and inelastic neutron scattering experiments. It is found that with increasing Rb content the system evolves from the gapped state at x=0, through a quantum phase transition at x∼0.35, and to the magnetically ordered state at larger x. Inelastic neutron experiments for x=0, x=0.3, and x=1 demonstrate that the magnetic anisotropy and spin interactions are continuously tuned by the chemical composition. Finally, for the intermediate concentration all magnetic excitations are substantially broadened suggesting that disorder plays a key role in this species. For the two end compounds, excitations remain sharp.

Insights into the evolution from ferromagnetism to antiferromagnetism: A doping-dependent study of ${NaCrSi}_{x} {Ge}_{2 - x} O_{6} (0 \leq x \leq 2)$

Journal Article Tian, Wei ; Yan, Jiaqiang ; Kolesnikov, Alexander I. - Physical Review B

NaCrGe₂O₆ and NaCrSi₂O₆ are isostructural compounds exhibiting different magnetic ground states. NaCrGe2O6 adopts a ferromagnetic ground state with Tc=6K, whereas NaCrSi₂O₆ orders antiferromagnetically below T_N=3.4K. Although it has been proposed that the intriguing magnetic behavior in Cr-based pyroxenes involves competition between antiferromagnetic direct exchange and ferromagnetic superexchange interactions, a delicate balance that is sensitive to Cr-Cr distance and local distortion, no spectroscopy study has been done to determine the microscopic interactions in these compounds. To delve deeper into the evolution from ferromagnetism to antiferromagnetism, we performed a doping-dependent study to investigate how the substitution of Ge by Si affects themore »« less

Journal Article Liu, Yaohua ; Sanjeewa, Liurukara D. ; Garlea, V. Ovidiu ; ... - Physical Review B

The macroscopic magnetic properties and microscopic magnetic structure of Rb₂Mn₃(MoO₄)₃ (OH)₂ (space group Pn ma) are investigated by magnetization, heat capacity, and single-crystal neutron diffraction measurements. The compound's crystal structure contains bond-alternating [Mn₃ O₁₁] ^∞ chains along the b axis, formed by isosceles triangles of Mn ions occupying two crystallographically nonequivalent sites (the Mn1 site on the base and Mn2 site on the vertex). These chains are only weakly linked to each other by nonmagnetic oxyanions. Both superconducting quantum interference device magnetometry and neutron diffraction experiments show two successive magnetic transitions as a function of temperature. On cooling, it transitionsmore »« less

Hidden order signatures in the antiferromagnetic phase of $U {({Ru}_{1 - x} {Fe}_{x})}_{2} {Si}_{2}$

Journal Article Williams, Travis J. ; Aczel, Adam A. ; Stone, Matthew B. ; ... - Physical Review B

We present a comprehensive set of elastic and inelastic neutron scattering measurements on a range of Fe-doped samples of U(Ru_1–xFe_x)₂Si₂ with 0.01 ≤ x ≤ 0.15. All of the samples measured exhibit long-range antiferromagnetic order, with the size of the magnetic moment quickly increasing to 0.51μB at 2.5% doping and continuing to increase monotonically with doping, reaching 0.69μB at 15% doping. Time-of-flight and inelastic triple-axis measurements show the existence of excitations at (1 0 0) and (1.4 0 0) in all samples, which are also observed in the parent compound. While the excitations in the 1% doping are quantitatively identicalmore »« less

Non-Fermi-liquid types of behavior associated with a magnetic quantum critical point in $Sr {({Co}_{1 - x} {Ni}_{x})}_{2} {As}_{2}$ single crystals

Journal Article Sangeetha, N. S. ; Wang, L. -L. ; Smirnov, A. V. ; ... - Physical Review B

The compound SrCo₂As₂ with the body-centered tetragonal ThCr₂Si₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo₂As₂. Previous work on polycrystalline samples of Sr (Co_1-x Ni_x)₂ As₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co_1-x Ni_x)₂ As₂ for 0 < x ≤ 1 and confirmed the occurrence of AFM order whichmore »« less
