Savigny a Bethmann-Hollweg, 27 agosto 1817: diritto e fede nella Historische Rechtsschule

2020

An unpublished letter written by Savigny to Bethmann-Hollweg in August 1817 provides a starting point for thinking about the relationship between the religious ideology of the Christian Revival (Erweckungsbewegung) , Prussian nationalism and the concept of law within the German Historical School.

The Future Of Mutual Assistance Conventions In The European Union

2010

The European Union, keeping to the traditional principles of conventional international law, dealt with judicial assistance within the framework provided by the Third Pillar, at first rather timidly through its new normative instruments; and then more effectively through the traditional route of conventions. The two main aims of the EU Convention 2000 are, on the one hand, 'ensuring that mutual assistance between Member States is provided in a fast and efficient manner'; 29 and on the other, guaranteeing that this is done in a way that is: 'compatible with the basic principles of their national law and in compliance with the individual rights and principles of the European Convention for th…

NQR/NMR and Mössbauer spectroscopy of sulfides: potential and versatility

2013

Nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR) and nuclear gamma-resonance (NGR or Mossbauer Effect) methods are generally described as highly sensitive tools in studies of local electronic structure and symmetry in solid-state materials. This is due to high informativity in electronic structure investigations, high resolution in phase-structural diagnostics (down to nano-scale), possibility to study polycrystalline and complex compounds, and to the non-destructive character of these methods. As applied to Earth sciences, both NQR/NMR and Mossbauer spectroscopy methods contribute to mineralogical material science and mineral physics. Another important aspect is the fac…

Investigation of ultrathin iron and iron/nickel layers prepared from Langmuir-Blodgett films

1996

Oxidic and metallic iron and iron/nickel multilayers, formed after thermal and chemical treatment of Langmuir-Blodgett films, were investigated. Reduced iron-stearate multilayers were compared with evaporated films concerning their phase composition and their lateral homogeneity. The sequence of metallic and oxidic iron in the films after reduction was determined. Oxidic iron/nickel mixed layers can be prepared from Langmuir-Blodgett films, in which a magnetically non-ordered Fe3+ phase exhibiting a distribution of the quadrupole splitting is observed. After reduction of such layers, two metallic iron phases appear dependent on the nickel concentration. The hyperfine field distribution of t…

Investigation of structure, stability, phase composition and magnetic ordering in ultrathin iron/nickel films

1995

By thermal and chemical treatment of Langmuir-Blodgett (LB) films, oxidic and metallic Fe and Ni layers can be prepared. The films are characterised, where differences e.g. in the lateral homogeneity are found. The metallic Fe containing samples show a higher corrosion stability as compared with films prepared by other coating techniques. Mixed Fe/Ni oxidic and metallic layers, respectively, are prepared, where the Ni concentration in the oxidic films can be determined as a function of the ratio of initially transferred numbers of LB layers. The phase composition of the metallic Fe changes systematically with the Ni concentration.

Mössbauer effect study of the electronic ground state of iron(II)in tris(2-chlorophenanthroline)iron(II) perchlorate

1976

Abstract Mossbauer spectra of [Fe(2-Cl-phen) 3 ](ClO 4 ) 2 ·H 2 O have been measured in the temperature range 293 − 5 K. The spectra indicate that the iron atom in this compound possesses a spin quintet ground state throughout the temperature range under study, in contradiction to the suggested high spin-low spin transition, which has been concluded from a magnetic susceptibility study by other authors. From a theoretical analysis of the temperature dependence of the quadrupole splitting, with trigonal distortion, spin-orbit coupling, and effects of covalency taken into account, the ground term of iron(II) in this compound has been elucidated as being 5 A 1 ( 5 T 2g ), separated from the 5 …

Magnetic properties of GdPdSb and GdNiSb studied by 155Gd-Mössbauer spectroscopy

2009

Abstract 155 Gd-Mossbauer spectroscopy was applied to study the magnetic properties of GdPdSb with hexagonal LiGaGe structure and of GdNiSb in the cubic MgAgAs-type structure as well as in the hexagonal AlB 2 -type structure. In GdPdSb magnetic ordering is observed at 13.0 K with indications of a tilted spin structure at lower temperatures. In the cubic phase of GdNiSb magnetic ordering is observed at 9.5 K and in the hexagonal phase around 3.5 K. These results are discussed in conjunction with previous investigations of these samples.
