In this thesis, the magnetic properties of self-assembled 3d and 4d metal nano-structures supported on surfaces have been investigated. The atomic coordination within the nano-structures was found to profoundly affect important quantities such as the magne ...
The soln. structure of the two intimate ion pairs present in soln. for [PtMe(h2-olefin)(a-diimine)]BF4 compds. (1-3, shown as I.BF4, R = Ph, 4-MeC6H4, 4-CF3C6H4) their relative abundance and the consequent thermodn. equil. parameters were detd. by a quant. ...
Combinatorial lithium niobate deposition on 150 mm naturally oxidized silicon (100) wafers in a high-vacuum chemical vapor deposition reactor using Li(OBut) and Nb(OEt)4(dmae) is presented. The novel precursor supply system allows individual spatial contro ...
We have investigated by angle-resolved photoemission spectroscopy changes induced by Xe adsorption on the spin-orbit-split bands of the epitaxial Ag(111) (root 3x root 3)R30 degrees-Bi surface alloy. We observe an extensive backfolding of the alloy band st ...
We report the 87Rb NMR results in a recently synthesized Na5RbCu4(AsO4)Cl2. This complex novel two-dimensional (2D) cuprate is an unique magnetic material, which contains layers of coupled Cu4O4 tetramers. In zero applied magnetic field, it orders antiferr ...
Nowadays, gold compounds constitute a family of very promising experimental agents for cancer treatment. Indeed, several gold(I) and gold(III) compounds were shown to manifest outstanding antiproliferative properties in vitro against selected human tumor c ...
Results of present and previous measurements of the23Na NMR response, dc- and ac-magnetic susceptibilities and the specific heat ofNa2V3O7at low temperatures suggest that this material is close to a quantum critical point (QCP) atm0H¼0 T. The experimental ...
The reproducible synthesis of the unusual ionic aluminum compd. [Tl3F2Al(OR)3]+[Al(OR)4]- (1) is reported. In the reaction of Li[Al(OR)4] [R = C(H)(CF3)2] with TlF the initially desired Tl[Al(OR)4] only formed with an exact 1:1 stoichiometry, while an exce ...
Transient absorption spectra of C60 mols. trapped in cryogenic rare gas matrixes and dissolved in room temp. toluene were measured with a time resoln. of 90 fs. An absorption build-up with a characteristic rise time of 200 fs is measured, which is solvent- ...
Mol.-dynamics simulations of structural relaxation in electronically excited NO-doped solid neon are presented. The NO impurity is excited to its lowest A (3ss) Rydberg state, inducing a rearrangement of the surrounding medium in the form of a bubble, due ...
