Electronic properties of the single crystal GdV6Sn6, where non-magnetic V-kagome layers are separated by magnetic Gd-triangular lattice, investigated. GdV6Sn6 exhibits unique magnetotransport at low-temperature such as non-linear Hall resistivity and increase resistance R in field H ~ H^0.75 up to 56 T with Shubnikov-De Haas oscillations. Investigation analogue YV6Sn6 first principles calculati...

A technique for the simultaneous measurement of three vascular parameters: blood flow (Frho), blood volume (v(b)), and the capillary permeability-surface area product (PSrho) in breast tumors using dynamic contrast-enhanced magnetic resonance imaging (MRI) is presented. Features of the technique include measurement of precontrast tumor T(1), rapid temporal sampling, measurement of the arterial ...

We study theoretically the dynamics of composite domain walls (DW) in multiferroic material GdFeO3 driven by magnetic field H. Two antiferromagnetic orders Fe and Gd spins Gd-ion displacement interact with each other this system coupling c at low temperatures. have numerically simulated corresponding time-dependent Ginzburg–Landau equations which H couples to Fe-spin order parameter. vary syste...

Lanthanide gadolinium (Gd(3+)) blocks Ca(V)1.2 channels at the selectivity filter. Here we investigated whether Gd(3+) block interferes with Ca(2+)-dependent inactivation, which requires Ca(2+) entry through the same site. Using brief pulses to 200 mV that relieve Gd(3+) block but not inactivation, we monitored how the proportions of open and open-blocked channels change during inactivation. We...

Using the lanthanide gadolinium (Gd(3+)) as a Ca(2+) replacing probe, we investigated the voltage dependence of pore blockage of Ca(V)1.2 channels. Gd(+3) reduces peak currents (tonic block) and accelerates decay of ionic current during depolarization (use-dependent block). Because diffusion of Gd(3+) at concentrations used (<1 microM) is much slower than activation of the channel, the tonic ef...

The title compound, tripotassium gadolinium(III) bis-[ortho-phosphate(V)], was synthesized by a high-temperature solution reaction. Of the 12 atoms of the asymmetric unit (1 × Gd, 2 × P, 3 × K, 6 × O), all but two O atoms (which are in general positions) lie on mirror planes. The crystal structure features sheets of composition [Gd(PO(4))(2)](3-) which extend parallel to (100) and are built up ...

Polycrystalline samples of Ca(1-x)Gd(x)MnO(3-δ) (x = 0.00, 0.02, and 0.05) have been studied by X-ray diffraction (XRD), electrical resistivity (ρ), thermoelectric power (S), and thermal conductivity (κ). All the samples were single phase with an orthorhombic structure. The Seebeck coefficient of all the samples was negative, indicating that the predominant carriers are electrons over the entir...

Let λKv be the complete multigraph with v vertices, where any two distinct vertices x and y are joined by λ edges (x, y). Let G be a finite simple graph. A G-design (G-packing, G-covering) of λKv, is denoted by (v,G, λ)-GD ((v,G, λ)-PD, (v,G, λ)-CD). In this paper, we determine the existence spectrum for the G-designs of λKv, λ > 1, and construct the maximum packings and the minimum coverings o...

Six new homodinuclear lanthanide(III) complexes with a flexible tripodal carboxylate ligand (H(3)L), of formulae [Ln(2)L(2)(DMF)(4)]·4DMF (Ln = La (1), Nd (2), Eu (3), Gd (4), Tb (5), Dy (6), DMF = N, N-Dimethylformamide) have been synthesized. Among them, 1, 2, 3, 4, 6 were characterized by single-crystal X-ray diffraction, which crystallized in the monoclinic space group P2(1)/n with a = 13.3...
