Abstract

Sr ₄Ru ₃O ₁₀, the n = 3 member of the Ruddlesden-Popper type ruthenate Sr _n+1Ru _n O _3n+1, is known to exhibit a peculiar metamagnetic transition in an in-plane magnetic field. However, the nature of both the temperature- and field-dependent phase transitions remains as a topic of debate. Here, we have investigated the magnetic transitions of Sr ₄Ru ₃O ₁₀ via single-crystal neutron diffraction measurements. At zero field, we find that the system undergoes a ferromagnetic transition with both in-plane and out-of-plane magnetic components at T _c ≈ 100 K. Below T * = 50 K, the magnetic moments incline continuously toward the out-of-plane direction. At T = 1.5 K, where the spins are nearly aligned along the c axis, a spin reorientation occurs above a critical field Bc, giving rise to a spin component perpendicular to the plane defined by the field direction and the c axis. We suggest that both the temperature- and field-driven spin reorientations are associated with a change in the magnetocrystalline anisotropy, which is strongly coupled to the lattice degrees of freedom. This study elucidates the long-standing puzzles on the zero-field magnetic orders of Sr ₄Ru ₃O ₁₀ and provides new insights into themore »« less

Electronic and magnetic properties of triple-layered ruthenate Sr{sub 4}Ru{sub 3}O{sub 10} single crystals grown by a floating-zone method

Journal Article Zhou, M. ; Hooper, J. ; Fobes, D. ; ... - Materials Research Bulletin

We have grown high-quality single crystals of the triple-layered perovskite ruthenate Sr{sub 4}Ru{sub 3}O{sub 10} using a floating-zone (FZ) method and measured their electronic transport and magnetic properties. Our experiments results are consistent with those previously reported for Sr{sub 4}Ru{sub 3}O{sub 10} flux crystals; the magnetic ground state of Sr{sub 4}Ru{sub 3}O{sub 10} is poised between an itinerant metamagnetic and itinerant ferromagnetic state, and its electronic ground state is a Fermi liquid. In addition, we have investigated the effect of disorder on the metallic state of Sr{sub 4}Ru{sub 3}O{sub 10}.

Field-induced magnetic phase transitions and memory effect in bilayer ruthenate Ca ₃Ru ₂O ₇ with Fe substitution

Journal Article Zhu, M. ; Hong, Tao ; Peng, J. ; ... - Journal of Physics. Condensed Matter

Bilayer ruthenate Ca ₃(Ru _1-xFe _x) ₂O ₇ (x = 0.05) exhibits an incommensurate magnetic soliton lattice driven by the Dzyaloshinskii–Moriya interaction. Here, in this work, we report complex field-induced magnetic phase transitions and memory effect in this system via single-crystal neutron diffraction and magnetotransport measurements. We observe first-order incommensurate-to-commensurate magnetic transitions upon applying the magnetic field both along and perpendicular to the propagation axis of the incommensurate spin structure. Furthermore, we find that the metastable states formed upon decreasing the magnetic field depend on the temperature and the applied field orientation. Lastly, we suggest that the observed field-induced metastabilitymore »« less

Mn-induced Ferromagnetic Semiconducting Behavior with Linear Negative Magnetoresistance in Sr ₄(Ru _1-xMn _x) ₃O ₁₀ Single Crystals

Journal Article Xing, Lingyi ; Gui, Xin ; Xie, Weiwei ; ... - Scientific Reports

Triple-layered Sr ₄Ru ₃O ₁₀ is a unique ferromagnet with the central RuO ₆ layer behaving differently from two outer layers both crystallographically and magnetically. Here, we report that the partial substitution of Ru by smaller Mn gives rise to modification in crystal structure, electronic and magnetic properties of Sr ₄(Ru _1-xMn _x) ₃O ₁₀. Through the single crystal X-ray diffraction refinement, we find that (Ru/Mn)O ₆ octahedral rotation is no longer detectable at x ≥ 0.23, leading to the tetragonal structure. The magnetization measurements indicate the ferromagnetic transition temperature T _C decreases from 105 K for x = 0more »« less

Missing magnetism in Sr ₄Ru ₃O ₁₀: Indication for Antisymmetric Exchange Interaction

Journal Article Weickert, Franziska ; Civale, Leonardo ; Maiorov, Boris ; ... - Scientific Reports

Metamagnetism occuring inside a ferromagnetic phase is peculiar. Therefore, Sr ₄Ru ₃O ₁₀, a T _C = 105 K ferromagnet, has attracted much attention in recent years, because it develops a pronounced metamagnetic anomaly below T _C for magnetic fields applied in the crystallographic ab-plane. The metamagnetic transition moves to higher fields for lower temperatures and splits into a double anomaly at critical fields H _c1 = 2.3 T and H _c2 = 2.8 T, respectively. Here, we report a detailed study of the different components of the magnetization vector as a function of temperature, applied magnetic field, and varyingmore »« less

In-depth study of the $H - T$ phase diagram of Sr ₄Ru ₃O ₁₀ by magnetization experiments

Journal Article Weickert, F. ; Civale, L. ; Maiorov, B. ; ... - Physica. B, Condensed Matter

Here, we present magnetization measurements on Sr ₄Ru ₃O ₁₀ as a function of temperature and magnetic field applied perpendicular to the magnetic easy c-axis inside the ferromagnetic phase. Peculiar metamagnetism evolves in Sr ₄Ru ₃O ₁₀ below the ferromagnetic transition T_C as a double step in the magnetization at two critical fields H _c1 and H _c2. We map the Sr ₄Ru ₃O ₁₀ - T phase diagram with special focus on the temperature range 50 K ≤ T ≤ T_C. We find that the critical field H _c1( T) connects the field and temperature axes of the phasemore »« less
