If anxiety-related disorders or depressive episodes occur along with tinnitus disease, psychiatric treatment can become necessary. Also, tinnitus coincides with psychoses. It has been shown that patients suffering from psychic disturbances can also d

Einleitung. Neben den typischen, anfallsweisen Drehschwindelattacken ist ein schwankendes Horvermogen im Tieftonbereich (zusammen mit einem meist tieffrequenten Tinnitus) definierter Bestandteil des Morbus Meniere. Tieftonschwankungen – auch ohne S

Iron-containing pyrochlores, having ions with various valencies on the B-sites, were investigated by magnetic measurements and Mossbauer spectroscopy. The influence of the ionic radius and of the valence state of the different cations accommodated on

The crystal structure of (Bi, Pb)-0212 was refined from neutron powder diffraction data at room temperature and 10 K as tetragonal (space group I4/mmm). The transition to superconductivity is not accompanied by a structural transition. Between the qu

A combined study of X-ray and neutron powder diffraction on (Pb 0.75 Cu 0.25 )Sr 2 Y 0.8 Ca 0.2 Cu 2 O z indicates that the rocksalt-like AO monolayers between the perovskite blocks are strongly distorted. By variation of the carrier concentration in

The crystal structure of Pb-0212 was refined from neutron powder diffraction data at room temperature and 8 K as tetragonal (space group I4/mmm). The transition to superconductivity is not accompanied by a structural rearrangement. The disadvantage o

The crystal structure of both Bi 0.5 Sr 1.5 YCu 1.5 Fe 0.5 O 6 and Sr 2 Pb 0.5 Y 0.5 CuFeO 6 is basically composed of double layers of (Cu,Fe)O 5 pyramids. In order to better understand the magnetic properties of this type of compound, a 57 Fe Mossba

In the system Bi-0212 the carrier concentration can be changed by both cation substitution and oxygen content. The crystal structure of Ca substituted material was refined from neutron powder diffraction data for Bi0.5Sr1.5Ca0.5Y0.5Cu1.5Fe0.5Oy. It i
