Polarized neutron study of the intermetallic conpound GdAl2

Journal of Magnetism and Magnetic Materials, 1983
Abstract We report the Gd magnetic form factor in GdAl2. In order to avoid the strong absorption of neutrons by natural gadolium very short wavelenghts were used. The 4f part of the form factor agrees with the relativistic radial integral 〈j0〉 calculated for a free ion, with a moment of only 6.6μB instead of the 7.0μB expected.

Polar‐Covalent Bonding Beyond the Zintl Picture in Intermetallic Rare‐Earth Germanides

Chemistry – A European Journal, 2019
AbstractA comparative chemical bonding analysis for the germanides La2MGe6 (M=Li, Mg, Al, Zn, Cu, Ag, Pd) and Y2PdGe6 is presented, together with the crystal structure determination for M=Li, Mg, Cu, Ag. The studied compounds adopt the two closely related structure types oS72‐Ce2(Ga0.1Ge0.9)7 and mS36‐La2AlGe6, containing zigzag chains and corrugated ...

Experimental and theoretical investigations of the polar intermetallics SrPt3Al2 and Sr2Pd2Al

Journal of Solid State Chemistry, 2016
Abstract SrPt3Al2, a CaCu5 relative (P6/mmm; a = 566.29(3), c = 389.39(3) pm; wR2 = 0.0202, 121 F2 values, 9 parameters), and Sr2Pd2Al, isostructural to Ca2Pt2Ge (Fdd2; a = 1041.45(5), b = 1558.24(7), c = 604.37(3) pm; wR2 = 0.0291, 844 F2 values, 25 parameters) have been prepared from the elements.

Effect of the Polarity of the III-V Intermetallic Compounds on Etching

Journal of Applied Physics, 1960
For the III-V intermetallic compounds, the <111> directions are polar axes. The shape of etch pits bounded by crystallographic planes and the presence or absence of pits at dislocations are influenced by the effect of the polar axes on the etch rates.

Electrocrystallization: A Synthetic Method for Intermetallic Phases with Polar Metal–Metal Bonding

Inorganic Chemistry, 2016
Isothermal electrolysis is a convenient preparation technique for a large number of intermetallic phases. A solution of the salt of a less-noble metal is electrolyzed on a cathode consisting of a liquid metal or intermetallic system. This yields crystalline products at mild reaction conditions in a few hours.

Novel Polar Intermetallic π-Systems along the Zintl Border

MRS Proceedings, 1998
AbstractStudies have shown that complex Zintl phases exhibit a rich diversity of crystal structures. These have also revealed a remarkable success of the Zintl concept in rationalizing stoichiometry, crystal structure and chemical bonding of many main group intermetallics.

Conduction electron spin polarization in some intermetallic europium compounds

Physica B+C, 1977
Abstract For the CaCu 5 -type compounds EuX 5 (X = Cu, Zn, Ag, Au) the magnetic properties, the lattice constants, the 151 Eu hyperfine fields and the isomer shifts were determined. The transferred hyperfine fields were estimated by means of data obtained on some pseudobinaries Eu 1− x R x X 5 (R = Ca, La, Gd).

β-Li₂Zn₅: A Low Symmetric Polar Intermetallic Compound

Inorganic Chemistry, 2019
The crystal structure of the high-temperature modification of the compound Li2Zn5 was determined using single-crystal X-ray diffraction data. It is the first representative of a new binary structure type with triclinic space group P1̅, where the parameters of the unit cell are a = 8.0073(3)Å, b = 11.5956(6)Å, c = 15.2956(5)Å, α = 96.39°, β = 101.92 ...
