The theory of Clogston and his coworkers on the line width of ferromagnetic resonance is derived by using thermodynamical retarded Green functions. The results obtained are applicable for a wide range of temperatures. The susceptibility tensor and the cha

This paper describes the fundamental problems of different types of photo-multiplier tubes for scintillation techniques, the relation between parameters of the multiplier-photo-tubes and their application. The status of photo-cathodes, secondary emissive

Several internal friction peaks were observed at high temperatures during torsion pendulum measurements in four types of high chromium steels and eight types of high chromium-nickel steels.An internal friction peak around 570℃ was observed in each of thre
