The phase transformation and magnetic properties of manganese bismuthide have been reinvestigated with single crystal samples of low temperature phase (LTP) and high temperature phase (HTP) in the quenched state (QHTP). It was established that the LTP and HTP are separate compounds with the chemical formulae MnBi and…
The nuclear magnetic resonance (NMR) of ${\mathrm{V}}^{51}$ has been studied in the series of compounds ${\mathrm{V}}_{1\ensuremath{-}x}{\mathrm{Cr}}_{x}{\mathrm{O}}_{2}$ between 100 and 350 K. Three insulating phases are clearly distinguished. In the low-temperature ${M}_{1}$ phase only one V site is seen with a posi…
A numerical method for the computation of electrostatic fields is described. The basis of the method is the use of fictitious line charges as particular solutions of Laplace's and Poisson's equations. Details are given of a digital computer program developed for field calculations by means of this method, and its appl…
Abstract Adjacent eu-latero-frontal cirri beat alternately and alternate cirri exhibit metachronous activity. Each cirrus consists of 22─26 pairs of cilia arranged in two parallel but alternating rows. Individual cilia leave the shaft of the cirrus at regular (0.6 μm) intervals on each side to extend across the interc…
The theory of thermal mixing between nuclear Zeeman interactions and electronic spin-spin interactions of impurities in dielectric solids, used to interpret the mixing between the Zeeman interactions of two nuclear spin species as the result of their separate coupling with the electronic spin-spin reservoir. The predi…
Abstract Ausgehend von Metallkomplexen 1a, 1f–1m des Octaatlylporphins [(OAP)MXY (M = Zn, Pd, Pt, Ga, In, Mn, Ti, V, Si)] wurden weitere (a,y‐Dimethyl‐a,y‐dihydrooctaathylporphinato)metallkomplexe 2f–2n [(OxPMe2)MXY (M = Pd, Pt, Ga, In, Mn, Ti, V, Si, Sn)] dargestellt und spektroskopisch charakterisiert. Die reduziere…
ZnO powder samples sized from 500 to 3 μm are annealed in reducing and oxidizing atmosphere, thus creating geometrical lattice defects which in the paramagnetic case can be detected with ESR. Predominantly oxygen vacancies, oxygen at interstitial sites, and the coupling of these two kinds of defects correlated to the…
Expansion due to illumination (photoexpansion) and contraction due to heat treatment (``thermal contraction'') of As–Se–(S)–Ge glass films have been observed utilizing the bimetal structures. This property is related to the reversible photodarkening effect of these chalcogenide glass films.
