Large-area antimony telluride (Sb2Te3) thin films are grown by a metal organic chemical vapor deposition technique on 4” Si(111) substrates, and their topological character probed magnetoconductance measurements. When interfaced with Fe films, broadband ferromagnetic resonance spectroscopy (BFMR) shows clear increase of the damping parameter in Fe/Sb2Te3 when compared to reference layer, which ...

— Biochemists routinely use UV/visible spectrophotometry as a means of identifying and measuring the quantity of many biological compounds. When a new type of compound is isolated however, the method is often unhelpful in determining its chemical nature, and other spectroscopic methods must be used. The iron-sulphur proteins have recently been recognised as major components of bioenergetic syst...

Eu3InP3 has been prepared as large single crystals with an indium flux reaction. The structure of the new compound is isotypic to Sr3InP3 and crystallizes in the orthorhombic space group Pnma with unit cell dimensions of a = 12.6517(15) A, b = 4.2683(5) A, and c = 13.5643(14) A (Z = 4, T = 140 K, R1 = 0.0404, wR2 = 0.0971 for all data). The structure consists of one-dimensional chains of corner...

(Cyclopentadienone)iron carbonyl complexes have recently received particular attention for their use as catalysts in hydrogenation or transfer reactions including the N-alkylation of amines with alcohols. This is due to easy synthesis from simple and cheap materials, air water stabilities, crucial metal-ligand cooperation giving rise unique catalytic properties. Here, we report a Mossbauer spec...

Isothermal crystallization of ternary (Ge,S,), -X(Sn,S,), glasses is examined over the glass forming range 0 < x < 0.6. Time-temperature-transformation (TIT) curves are obtained using scanning calorimetry. The results show that both nucleation and growth processes dominate crystallization of the glasses in the range 0 < .Y < 0.25, but only growth processes are found to occur once x 2 0.25. The ...

Mossbauer effect has been observed for disordered and ordered Fel-,Pdx alloys. The internal field and the quadrupole and isomer shifts were obtained. The asymmetrical spectrum for 0.45 < x < 0.75 and the temperature dependence of isomer shifts for x = 0.32 were interpreted as a distribution of the quadrupole field and a second order Doppler effect respectively. With respect to the invar effect ...
