Polycrystalline substances of the type La 1 —δSr δ MnO 3 have been investigated. These are
ferromagnetic semiconductors which exhibit some remarkable second order effects related …

Of Terrestrial Magnetism. The protons scattered from a thin carbon target on a silver leaf
backing were counted with an argonfilled proportional counter biased to count only those …

The thermal conductivity of single crystalline BaTiO 3 has been measured in the temperature
range of 100–500K. In the neighbourhood of the transition temperature a reduction of the …

In this paper measurements of the thermal conductivity of barium titanate between 2 and
100 K are presented. In the discussion of these measurements it appears that phonon …

Resistivity, Hall-and Seebeck-data of reduced and lithium-doped rutile both with and without
alumina added are reported. The data are interpreted by a one band model. Anisotropy of …

In various fields of research a considerable demand has arisen in recent years for stationary
magnetic fields of exceptional strength. In solid-state, research, for example, it would be …

The mean internal field is equal to 8, but fields alternating with distance are superposed. These
fields and also the effect (b) cannot give a finite psrr in a periodic lattice (pure metal at T= …

RECENTLY, some observations have been published of phenomena related to the second-order
transition of chromium oxide (Cr 2 O 3 ) at the antiferromagnetic Curie temperature; for …

At low temperatures smoky quartz crystals present high dielectric loss peaks in the audio and
radio frequency range. The dielectric relaxational behaviour between 2 and 170 K can be …
