Abstract

Zero-field unpolarized neutron powder diffraction has been used to study the low-T magnetic structure and {ital T}-dependent crystal structure of M[N(CN){sub 2}]{sub 2} (M=Co,Ni). Both compounds show collinear ferromagnetism with spin orientation along the {ital c} axis. The results provide the determination of a complete magnetic structure in the ordered state for a molecule-based magnet. The {ital c} lattice parameter exhibits negative thermal expansion, explained by a wine-rack-like deformation. {copyright} {ital 1999} {ital The American Physical Society}

Noncollinear antiferromagnetic structure of the molecule-based magnet Mn[N(CN){sub 2}]{sub 2}

Journal Article Kmety, Carmen R ; Huang, Qingzhen ; Department of Materials and Nuclear Engineering, University of Maryland, College Park, Maryland 20742 ; ... - Physical Review. B, Condensed Matter and Materials Physics

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.

Spontaneous magnetization in the M[N(CN){sub 2}]{sub 2} (M = Cr, Mn) weak ferromagnets

Journal Article Manson, J L ; Miller, J S ; Kmety, C R ; ... - Inorganic Chemistry

Due to stabilization of relatively strong magnetic coupling, multidimensional coordination polymers consisting of transition metal cations and the dicyanamide ligand. [N(CN){sub 2}]{sup {minus}}, are currently being studied. Homoleptic dicyanamide complexes with octahedral metal sites from 3-D rutile-type architectures. M[N(CN){sub 2}]{sub 2} (M = Co, Ni) exhibit ferromagnetic ordering at 9 and 21 K, respectively, and have been further characterized by neutron diffraction and specific heat measurements. In contrast, interpenetrating M[C(CN){sub 3}]{sub 2} (M = Mn, Fe, Co, Ni, Cu) also have rutile-type networks, but exhibit weak antiferromagnetic coupling while M = V and Cr are strongly antiferromagnetically coupled and exhibitmore »« less

Field-dependent antiferromagnetism and ferromagnetism of the two copper sublattices in Sr{sub 2}Cu{sub 3}O{sub 4}Cl{sub 2}

Journal Article Kastner, M A ; Aharony, A ; School of Physics and Astronomy, Raymond and Beverly Sackler Faculty of Exact Sciences, Tel Aviv University, Tel Aviv 69978 ; ... - Physical Review, B: Condensed Matter

The Cu{sub 3}O{sub 4} layer in Sr{sub 2}Cu{sub 3}O{sub 4}Cl{sub 2} is a variant of the square CuO{sub 2} lattice of the high-temperature superconductors, in which the center of every second plaquette contains an extra Cu{sup 2+} ion. The ions that make up the conventional CuO{sub 2} network, called CuI, have CuI-CuI exchange energy {approx}130thinspmeV, and order antiferromagnetically at about 380 K; the CuII-CuII exchange is only {approx}10thinspmeV, and the CuII{close_quote}s order at {approx}40thinspK. A study is reported here of the dependence of the magnetization on field, temperature, and crystallographic orientation for this interesting system. We show that the smallmore »« less

Pr and Cu magnetism in (Pr{sub 1.5}Ce{sub 0.5})Sr{sub 2}Cu{sub 2}MO{sub 10{minus}{delta}} (M=Nb, Ta): Correlations with a suppression of superconductivity

Journal Article Goodwin, T J ; Shelton, R N ; Radousky, H B ; ... - Physical Review, B: Condensed Matter

The magnetic properties of nonsuperconducting (Pr{sub 1.5}Ce{sub 0.5})Sr{sub 2}Cu{sub 2}MO{sub 10{minus}{delta}} with M=Nb, Ta are characterized with dc magnetization, specific-heat, and neutron-diffraction experiments. Data for (Pr{sub 1.5}Ce{sub 0.5})Sr{sub 2}Cu{sub 2}NbO{sub 10{minus}{delta}} reveal complex Cu magnetism marked by antiferromagnetic order below 200 K, spin structure transitions at 130 and 57 K, both collinear and noncollinear antiferromagnetic spin structures, and weak ferromagnetic behavior below 130 K. The data also indicate an anomalous ordering of the Pr spins near 10 K, a large linear contribution to the low-temperature specific heat, and a Pr 4f crystal-field ground state similar to that found in PrBa{submore »« less

Two isotypic diphosphates LiM{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (M=Ni, Co) containing ferromagnetic zigzag MO{sub 6} chains

Journal Article Tao, Yang ; Sihai, Yang ; Fuhui, Liao ; ... - Journal of Solid State Chemistry

Two new isotypic phosphates LiNi{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (1) and LiCo{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (2) have been hydrothermally synthesized and structurally characterized by the single-crystal X-ray diffraction technique. They crystallize in the monoclinic space group C2/c with the lattice: a=10.925(2) A, b=12.774(3) A, c=8.8833(18) A, {beta}=123.20(3){sup o} for 1 and a=10.999(2) A, b=12.863(3) A, c=8.9419(18) A, {beta}=123.00(3){sup o} for 2. The transition metal atoms are octahedrally coordinated, whereas the lithium and phosphorus atoms are all tetrahedrally coordinated. As the lithium-induced derivatives of MH{sub 2}P{sub 2}O{sub 7} (M=Ni, Co), 1 and 2 possess the same structure withmore »« less
