We have experimentally identified a new magnetic ground state for the kagome lattice, in the perfectly hexagonal Fe2+ (3d6, S = 2) compound Fe4Si2Sn7O16. Representational symmetry analysis of neutron diffraction data shows that below T_N = 3.5 K, the

Magnetic spiral structures can exhibit ferroelectric moments as recently demonstrated in various multiferroic materials. In such cases the helicity of the magnetic spiral is directly correlated with the direction of the ferroelectric moment and measu

Inhomogeneous Magnetism in La-doped CaMnO3. (II) Mesoscopic Phase Separation due to Lattice-coupled FM Interactions

Autor: Ling, C. D., Granado, E., Neumeier, J. J., Lynn, J. W., Argyriou, D. N.

A detailed investigation of mesoscopic magnetic and crystallographic phase separation in Ca(1-x)La(x)MnO3, 0.00<=x<=0.20, is reported. Neutron powder diffraction and DC-magnetization techniques have been used to isolate the different roles played by

Glass Transition in the Polaron Dynamics of CMR Manganites

Autor: Argyriou, D. N., Lynn, J. W., Osborn, R., Campbell, B., Mitchell, J. F., Ruett, U., Bordallo, H. N., Wildes, A., Ling, C. D.

Neutron scattering measurements on a bilayer manganite near optimal doping show that the short-range polarons correlations are completely dynamic at high T, but then freeze upon cooling to a temperature T* 310 K. This glass transition suggests that t

The Structure of Nanoscale Polaron Correlations in La1.2Sr1.8Mn2O7

Autor: Campbell, B. J., Osborn, R., Argyriou, D. N., Vasiliu-Doloc, L., Mitchell, J. F., Sinha, S. K., Ruett, U., Ling, C. D., Islam, Z., Lynn, J. W.

Publikováno v: Phys. Rev. B 65, 014427 (2002)

A system of strongly-interacting electron-lattice polarons can exhibit charge and orbital order at sufficiently high polaron concentrations. In this study, the structure of short-range polaron correlations in the layered colossal magnetoresistive per

Interplay of spin and orbital ordering in the layered colossal magnetoresistance manganite La2-2xSr1+2xMn2O7 (0.5<=x<=1.0)

Autor: Ling, C. D., Millburn, J. E., Mitchell, J. F., Linton, D. N. Argyriou J., Bordallo, H. N.

The crystallographic and magnetic phase diagram of the n=2 layered manganite La2-2xSr1+2xMn2O7 in the region x=>0.5 has been studied using temperature dependent neutron powder diffraction. The magnetic phase diagram reveals a progression of ordered m

Magnetic anisotropy and spin dynamics in the kagome magnet Fe4Si2Sn7O16: NMR and magnetic susceptibility study on oriented powder

Autor: Dengre, S., Sarkar, R., Opherden, L., Herrmannsdörfer, T., Allison, M., Söhnel, T., Ling, C. D., Gardner, J. S., Klauss, H.-H.

Publikováno v: Physical Review B 103(2021), 064425

Fe4Si2Sn7O16 hosts an undistorted kagome lattice of Fe2+ (3d6, S = 2) ions. We present results of bulk magnetization and Sn nuclear magnetic resonance (NMR) measurements on an oriented Fe4Si2Sn7O16 powder sample oriented in geometries parallel (II) a
