Spin Chemistry of Guest@Host Systems: H₂@C₆₀ and Nitroxide@Octa Acid
… of nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy. The first chapter describes the background and motivation of our scientific pursuit. Chapters 2-4 describe the nuclear spin chemistry of the two allotropes of elemental hydrogen, para-H₂ and ortho-H₂, …

Magnetic ordering and spin wave dynamics in transition metal arsenides
… the two-step transition in Mn3As2 from a paramagnet to a collinear ferrimagnet and then, into a canted spin state. Using high resolution synchrotron x-ray diffraction and neutron powder diffraction measurements, we identify magnetically coupled structural transitions in tetragonal CuMnAs …

Synthesis and characterisation of materials with potential multiferroic behaviour
… appears to be a paramagnet. Failure to produce Bi\(_5\)MnTi\(_3\)O\(_1\)\(_5\) , by other researchers methods, raises doubts about manganese substitution into the bismuth-layer structure.

Dynamics in quantum spin glass systems
… space (HSGS). The critical temperatures of the paramagnet to spin glass phase transitions are determined accurately. Compared to the spin-static results, the dynamics causes slight increases of T_c by about 3% and 2%, respectively. For the HSGS the specific heat C(T) is investigated in the …

Low temperature Kerr effect study of magnetic topological insulators and other magnetic structures
… the MOKE microscope. Regarding the ferromagnet/paramagnet [Cr:Sb$_2$Te$_3$/Dy:Bi$_2$Te$_3$]$_{10}$ superlattice film, unexpected exchange bias is observed in the material with an exchange field of up to 0.15 T at 10 K. This finding is supported by a density-functional-theory calculation. Apart …

Substitution and Disorder Effects in Ternary Intermetallics
… the main group site. The Yb analogues are Pauli paramagnets with the Yb ion adopting an electronic configuration close to Yb2+, while the Gd analogues show paramagnetic behavior with no magnetic order down to 3 K. The synthesis and characterization of Sm1.33Pd3Ga8 is reported. Sm1.33Pd3Ga8 adopts …

Surface Deformations of Magnetic Continua in Homogeneous Fields
… of these substances are similar to a usual paramagnet with the important difference, that the susceptibility of the former is higher by a factor of 10^3 to 10^6. By the application of a homogeneous field, a transformation of the shape of a magnetic sample can be induced. In this thesis, four …

Synthesis and Characterization of Heusler Compounds with Non-Collinear Magnetic Structure - From Spin Glasses to Spin Reorientation
… and Ru2CrSb. Ru2CrGa was identified as Pauli paramagnet whereas Ru2CrSb exhibited an antiferromagnetic transition around 100 K. A second transition at 40 K was accompanied by a small increase of magnetization, which hinted on some more complex magnetic structure at low temperatures.

Synthesis, characterization and chemical vapor deposition of transition metal di(tert-butyl)amido compounds
Although the transition metal chemistry of many dialkylamido ligands has been well studied, the chemistry of the bulky di(tert-butyl)amido ligand has been largely overlooked. The di(tert-butyl)amido ligand is well suited for synthesizing transition metal compounds with low coordination numbers; …
