Title: Magnetization dynamics and frustration in the multiferroic double perovskite Lu₂MnCoO₆

Abstract

Here, we investigate the magnetic ordering and the magnetization dynamics (from kHz to THz time scales) of the double perovskite Lu₂MnCoO₆ using elastic neutron diffraction, muon spin relaxation, and micro-Hall magnetization measurements. This compound is known to be a type II multiferroic with the interesting feature that a ferromagneticlike magnetization hysteresis loop couples to an equally hysteretic electric polarization in the bulk of the material despite a zero-field magnetic ordering of the type ↑↑↓↓ along Co-Mn spin chains. Here we explore the unusual dynamics of this compound and find extremely strong fluctuations, consistent with the axial next-nearest-neighbor Ising (ANNNI) model for frustrated spin chains. We identify three temperature scales in Lu₂MnCoO₆ corresponding to the onset of highly fluctuating long-range order below T_N = 50±3 K identified from neutron scattering, the onset of magnetic and electric hysteresis, with change in kHz magnetic and electric dynamics below a 30 K temperature scale, and partial freezing of ~MHz spin fluctuations in the muon spin relaxation data below 12 ± 3 K. Our results provide a framework for understanding the multiferroic behavior of this compound and its hysteresis and dynamics.

Electric polarization observed in single crystals of multiferroic ${Lu}_{2} {MnCoO}_{6}$

Journal Article Chikara, Shalinee ; Singleton, John ; Bowlan, John M. ; ... - Physical Review B

We report electric polarization and magnetization measurements in single crystals of double perovskite Lu₂MnCoO₆ using pulsed magnetic fields and optical second harmonic generation in dc magnetic fields. We observe well-resolved magnetic field-induced changes in the electric polarization in single crystals and thereby resolve the question about whether multiferroic behavior is intrinsic to these materials or is an extrinsic feature of polycrystals. We find electric polarization along the crystalline b axis, that is suppressed by applying a magnetic fields along the c axis, and advance a model for the origin of magnetoelectric coupling. We furthermore map the phase diagram using bothmore »« less

Frustration and multiferroic behavior in Ca3CoMnO6

Conference Zapf, Vivien

Lu{sub 2}MnCoO{sub 6} and Ca{sub 3}MnCoO{sub 6} satisfy one of the primary goals of multiferroics research, namely ferromagnetic-like magnetization coupled to ferroelectric-like polarization. Thus the mechanism for magnetoelectric coupling in these materials deserves careful study. New data shows that the physics of these compound may be related to the classic 'ANNNI' model. Frustration between ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor interactions between Ising spins creates an 'up up down down' magnetic structure in zero magnetic field, along c-axis chains that consist of alternating Co and Mn ions. In applied magnetic fields 'up up down,' 'up up up down' and other metastablemore »« less

Spin dynamics in pure and Zn-doped CuGeO{sub 3} by muon spin relaxation: Spin-Peierls and spin-glass transitions

Journal Article Garcia-Munoz, J L ; Suaaidi, M ; Martinez, B - Physical Review, B: Condensed Matter

Zero and longitudinal muon spin relaxation has been used to characterize the spin dynamics of local magnetic moments in the quasi-one-dimensional {ital S}=1/2 cuprates CuGeO{sub 3} and Cu{sub 0.96}Zn{sub 0.04}GeO{sub 3}. Frozen moments are not observed in CuGeO{sub 3}, only a slowing down of the fluctuating rate of Cu moments was seen below 14 K. Magnetic measurements in the slightly doped sample confirm the suppression of the spin-singlet transition, and the appearance of hysteresis between the zero-field-cooled and field-cooled branches of the magnetic susceptibility below {ital T}{approx}4.5 K, both absent in the pure compound. The depolarization of muons gives evidencemore »« less

Magnetic properties and critical behavior of Fe(tetracyanoethylene){sub 2}(centre dot)x(CH{sub 2}Cl{sub 2}): A high-T{sub c} molecule-based magnet

Journal Article Girtu, Mihai A ; Wynn, Charles M ; Zhang, Jie ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report magnetic studies of Fe(TCNE){sub 2}{center_dot}x(CH{sub 2}Cl{sub 2}), a member of the family of high-T{sub c} molecule-based magnets, M(TCNE){sub x}{center_dot}y(solvent) (M=V, Mn, TCNE=tetracyanoethelyne). Based on extensive static and dynamic magnetic measurements we show that this system has a complex magnetic behavior, with a mixture of ferrimagnetic and random anisotropy characteristics. The constricted hysteresis curve with a spin-flop shape, the ac susceptibility in the presence of a dc field, consistent with the spin-flop picture, and the remanent magnetization suggest ferrimagnetic behavior. The ac susceptibility data in zero dc field have modest frequency dependence suggesting glassiness, while the field-cooling/zero-field-cooling magnetization datamore »« less

mu. SR measurement of rare-earth moment dynamics in the Ho/sub x/Lu/sub 1-x/Rh/sub 4/B/sub 4/ ternary alloy system

Journal Article Boekema, C ; Heffner, R H ; Hutson, R L ; ... - J. Appl. Phys.; (United States)

..mu..SR measurements have been carried out in the ternary rare-earth system Ho/sub x/Lu/sub 1-x/Rh/sub 4/B/sub 4/, x = 0, 0.7, and 1, to study the effects of superconductivity and magnetic order on Ho moment dynamics in this alloy series. In nonmagnetic LuRh/sub 4/B/sub 4/, muon relaxation is due to nuclear dipolar fields; the decrease of the relaxation rate above approx.200 K is attributed to the onset of muon diffusion at this temperature. In HoRh/sub 4/B/sub 4/, the zero-field relaxation rate ..lambda..(T) exhibits a strong maximum well above the magnetic ordering temperature T/sub M/ = 6.6 K, but no singularity atmore »« less
