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 SrCo ₂As ₂ with the body-centered tetragonal ThCr ₂Si ₂ 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 SrCo ₂As ₂. Previous work on polycrystalline samples of Sr (Co _1-x Ni _x) ₂ As ₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co _1-x Ni _x) ₂ As ₂more »« less

Manganese-induced magnetic symmetry breaking and its correlation with the metal-insulator transition in bilayered $S r_{3} {(R u_{1 - x} M n_{x})}_{2} O_{7}$

Journal Article Zhang, Qiang ; Ye, Feng ; Tian, Wei ; ... - Physical Review B

Bilayered Sr ₃Ru ₂O ₇ is an unusual metamagnetic metal with inherently antiferromagnetic (AFM) and ferromagnetic (FM) fluctuations. Partial substitution of Ru by Mn results in the establishment of a metal-insulator transition (MIT) at TMIT and AFM ordering at TM in Sr ₃(Ru _1-xMn _x) ₂O ₇. Using elastic neutron scattering, we investigated the effect of Mn doping on the magnetic structure, in-plane magnetic correlation lengths and their correlation to the MIT in Sr ₃(Ru _1-xMn _x) ₂O ₇ (x=0.06 and 0.12). With the increase of Mn doping (x) from 0.06 to 0.12 or the decrease of temperatures for x=0.12,more »« less

Ultrafast optical pump-probe spectroscopy is used to reveal the coexistence of coupled antiferromagnetic (AFM)/ferroelectric (FE) and ferromagnetic (FM) orders in multiferroic TbMnO3 films, which can guide researchers in creating new kinds of multiferroic materials.

Conference Qi, Jingbo ; Zhu, Jianxin ; Trugman, Stuart A ; ...

Multiferroic materials have attracted much interest in the past decade, due not only to their novel device applications, but also their manifestations of coupling and interactions between different order parameters (particularly electric polarization and magnetic order). Recently, much attention has been focused on perovskite manganites, RMnO{sub 3} (R = rare earth ions), due to the discovery of a large magnetoelectric effect in these materials. The first member of this family to be discovered was TbMnO{sub 3} (TMO), which is now well established as a typical magnetoelectric multiferroic. Extensive experimental and theoretical studies have already been done on single crystal TMOmore »« less

7 9 : ; : < at.% Pu in Y was produced as microspheres by passing powdered particles of the alloy through the induction-coupled plasma torch. This alloy is one of the few solid-solution alloys of Pu which melt above the melting point of Pu metal. The microspheres have potential application as the fissile particles in dispersion type fuels. Unlike pure Pu the shiny particles retained their original appearance on continuous exposure to laboratory air. Metallographic examination of cross-sectioned microspheres indicated a uniform single phase, the solid solution. Metallographic work on the Ce-- Pu binary system was completed.

Theory of static and resonance properties of magnetically ordered phases of high-T sub c superconductors in a magnetic field II. RBa sub 2 Cu sub 3 O sub 6+. delta

Journal Article Bar'yakhtar, V G ; Loktev, V M ; Yablonskii, D A - Superconductivity; (USA)

The spin configurations, frequencies, and polarizations of antiferromagnetic (AFM) and antiferroelectric (AFE) resonances have been calculated, on the basis of symmetry analysis, for magnetically ordered phases of crystals of the type RBa{sub 2}Cu{sub 3}O{sub 6+{delta}} ({delta}{le}0.4). It is shown that the invariants which characterize the ground-stainclude those which are responsible for an incommensurate structure. The conditions for the formation of this structure are determined. The field dependence of the resonance frequencies in the transverse and longitudinal magnetic fields (with respect to the ground-state antiferromagnetism vector) has been determined for a homogeneous structure.
