Abstract

The crystallographic and magnetic properties of the Mn[N(CN){sub 2}]{sub 2} compound have been investigated by dc magnetization, ac susceptibility, specific heat, and zero-field neutron diffraction on polycrystalline samples. The magnetic structure consists of two sublattices which are antiferromagnetically coupled and spontaneously canted. The spin orientation is mainly along the a axis with a small uncompensated moment along the b axis. The ground state is a crystal-field sextet with large magnetic anisotropy. The crystal structure consists of discrete octahedra which are axially elongated and successively tilted in the ab plane. Comparisons of the magnetic structures for the isostructural M[N(CN){sub 2}]{sub 2} (M=Mn, Fe, Co, Ni) series suggest that the spin direction is stabilized by crystal fields and the spin canting is induced by the successive tilting of the octahedra. We propose that the superexchange interaction is the mechanism responsible for the magnetic ordering in these compounds and we find that a crossover from noncollinear antiferromagnetism to collinear ferromagnetism occurs for a superexchange angle of {alpha}{sub c}=142.0(5) degree sign .

Structural and magnetic properties of La{sub 1-x}Pr{sub x}MnO{sub 3+{delta}} (0{<=}x{<=}1.0)

Journal Article Dyakonov, V ; A. A. Galkin Donetsk Physico-Technical Institute NASU, 83114 Donetsk ; Bukhanko, F ; ... - Physical Review. B, Condensed Matter and Materials Physics

X-ray, neutron powder diffraction (NPD), and magnetic measurements were performed in order to investigate the effect of Pr substitution for La on crystallographic structure, on character of magnetic ordering, and on transition temperature in La{sub 1-x}Pr{sub x}MnO{sub 3+{delta}} manganites series (0{<=}x{<=}1.0). Strong dependence of structural and magnetic properties on average A-site ionic radius was found. The magnetic phase diagram, characterizing Pr concentration dependence of the phase transition temperature, was constructed, based on magnetic and on NPD results. In the compounds with x<0.7, the ferromagneticlike behavior with ferromagnetic moment aligned along the b axis was observed in the temperature interval belowmore »« less

Long-range magnetic order in Mn[N(CN)2]2(pyz) {pyz = pyrazine}. susceptibility, magnetization, specific heat and neutron diffraction measurements and electronic structure calculations.

Journal Article Manson, J L ; Huang, Q -Z ; Lynn, J W ; ... - J. Am. Chem. Soc.

Using dc magnetization, ac susceptibility, specific heat, and neutron diffraction, we have studied the magnetic properties of Mn[N(CN){sub 2}]{sub 2}(pyz) (pyz = pyrazine) in detail. The material crystallizes in the monoclinic space group P2{sub 1}/n with a = 7.3248(2), b = 16.7369(4), and c = 8.7905(2) {angstrom}, {beta} = 89.596(2){sup o}, V = 1077.65(7) {angstrom}{sup 3}, and Z = 4, as determined by Rietveld refinement of neutron powder diffraction data at 1.35 K. The 5 K neutron powder diffraction data reflect very little variation in the crystal structure.

Experimental and theoretical characterization of the magnetic properties of CuF{sub 2}(H{sub 2}O){sub 2}(pyz) (pyz = pyrazine) : a two-dimensional quantum magnet arising from super-superexchange interactions through hydrogen bonded paths.

Journal Article Manson, J L ; Conner, M C ; McConnell, A C ; ... - J. Am. Chem. Soc.

The structural, electronic, and magnetic properties of the new linear chain coordination polymer CuF{sub 2}(H{sub 2}O){sub 2}(pyz) (pyz = pyrazine) were determined by single crystal X-ray diffraction at various temperatures, SQUID magnetometry, pulsed-field magnetization, ESR, muon-spin relaxation ({mu}SR), and electronic structure calculations. Each Cu{sup 2+} ion of CuF{sub 2}(H{sub 2}O){sub 2}(pyz) is located at a distorted CuF{sub 2}O{sub 2}N{sub 2} octahedron with axial elongation along the Cu?N bonds. These octahedra are tethered together by strong F...H-O hydrogen bonds to yield two-dimensional (2D) square nets in the bc-plane that are linked along the a-direction by pyrazine linkages.
