Sr2Pt8−x As: a layered incommensurately modulated metal with saturated resistivity

László Forró, Oleg Yazyev, Alla Arakcheeva, Philip Johannes Walter Moll, Gabriel Albert Autes, Andrea Pisoni, Sergiy Katrych, Maja Deborah Bachmann, Edoardo Martino

The high-pressure synthesis and incommensurately modulated structure are reported for the new compound Sr2Pt8-xAs, with x = 0.715 (5). The structure consists of Sr2Pt3 As layers alternating with Pt-only corrugated grids. Ab initio calculations predict a me ...

Reversible Segregation of Nickel from Perovskite-type Oxides - Applications in Energy Processes

Patrick Simon Steiger

In this thesis, Ni catalysts derived from perovskite-type metal oxides (PMO, general formula ABO3, A=lanthanide or earth alkaline element, B=transition metal) are investigated as a potential class of materials, which are able to overcome thechallenges of c ...

Controlling the helicity of magnetic skyrmions in a beta-Mn-type high-temperature chiral magnet

Henrik Moodysson Rønnow, Jonathan White

Magnetic helices and skyrmions in noncentrosymmetric magnets are representative examples of chiral spin textures in solids. Their spin swirling direction, often termed as the magnetic helicity and defined as either left handed or right handed, is uniquely ...

Kinetics of Ion-Exchange Reactions in Hybrid Organic-Inorganic Perovskite Thin Films Studied by In Situ Real-Time X-ray Scattering

Mohammad Ibrahim Dar, Neha Arora

The exchange of ions in hybrid organic inorganic perovskites with the general formula APbX(3) (A = MA, FA; X = I, Cl, Br) is studied in five different systems using in situ real-time grazing incident X-ray diffraction (GIXD). In systems where the organic c ...

Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters

Aparajita Singha

This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...

Building Composite Iron-Manganese Oxide Flowerlike Nanostructures: A Detailed Magnetic Study

Davide Deiana

Here we show that it is possible to produce different magnetic core multiple shell heterostructures from monodisperse Fe3O4 spherical magnetic seeds by finely controlling the amount of a manganese precursor and using, in a smart and simple way, a cation-ex ...

J1−J2 square-lattice Heisenberg antiferromagnets with 4d1 spins: AMoOPO4Cl (A=K,Rb)

Henrik Moodysson Rønnow, Peter Babkevich

Magnetic properties of AMoOPO4Cl (A=K,Rb) with Mo5+ ions in the 4d1 electronic configuration are investigated by magnetization, heat capacity, and nuclear magnetic resonance (NMR) measurements on single crystals, combined with powder neutron diffraction ex ...
