Manganese silicide nanowires via metallic flux nanonucleation: growth mechanism and temperature-dependent resistivity.

MnSinanowires are believed to be the building blocks of the newest trends of flexible and stretchable devices in nanoelectronics. In this context , growing MnSinanowires, as well as characterizing their electronic transport properties provide insight into their phenomenology. In this work, we report on the growth mechanism of MnSinanowires produced by the metallic flux nanonucleation method, as well as the resistivity measurements of these nanostructures.

Electronic and magnetic properties of stoichiometric CeAuBi.

We report the electronic and magnetic properties of stoichiometric CeAuBi single crystals. At ambient pressure, CeAuBi orders antiferromagnetically below a Néel temperature ( ) of 19 K. Neutron diffraction experiments revealed an antiferromagnetic propagation vector , which doubles the paramagnetic unit cell along the axis.

Low-temperature electronic transport of manganese silicide shell-protected single crystal nanowires for nanoelectronics applications.

Recently, core-shell nanowires have been proposed as potential electrical connectors for nanoelectronics components. A promising candidate is MnSi nanowires encapsulated in an oxide shell, due to their low reactivity and large flexibility. In this work, we investigate the use of the one-step metallic flux nanonucleation method to easily grow manganese silicide single crystal oxide-protected nanowires by performing their structural and electrical characterization.

Evolution of the magnetic properties in the antiferromagnet CeRhIn simultaneously doped with Cd and Ir.

We report the evolution of the magnetic properties of single crystals. In particular, for () and (), we have solved the magnetic structure of these compounds using single-crystal neutron magnetic diffraction experiments. Taking the magnetic structure of the heavy-fermion antiferromagnet as a reference, we have identified no changes in the magnetic wave vector; however, the direction of the ordered Ce moments rotates toward the plane, under the influence of both dopants.

Tuning the crystalline electric field and magnetic anisotropy along the series.

We have performed X-ray powder diffraction, magnetization, electrical resistivity, heat capacity and inelastic neutron scattering (INS) to investigate the physical properties of the intermetallic series of compounds . These compounds crystallize in a tetragonal structure with space group and present antiferromagnetic transition temperatures ranging from 3.6 K to 16 K.
