Magnetic and magnetoelastic properties of Fe64Co21B15 and Fe73Co12B15 amorphous metal strips

The effect of magnetic annealing on the magnetic and magnetoelastic properties of FeCoB amorphous metal strips in the temperature range from 290 to 380°C has been investigated. With the method of photostimulated exoelectronic emission it has been found that in this temperature range there occurs crystallization of the surface of the test strips. It has been shown that the minima of the coercive force, residual induction, and differential magnetic permeability and the maximum absolute values of the negative Δ-effect are attained at magnetic annealing temperatures close to the temperatures corresponding to the maxima of the intensity of photostimulated exoelectronic emission. An explanation of the results obtained has been proposed which is based on the notions about the effect of internal stresses on the induced magnetic anisotropy of the test strips. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 59–65, August, 2006.     

Catalytic phosphorylation of polyfluoroalkanols. 11. α-Polyfluoroalkylbenzyldichlorophosphates as phosphorylating agents in the catalytic phosphorylation of primary polyfluoroalkanols

Conclusions -Polyfluoroalkylbenzyldichlorophosphates react, in the presence of catalytic quantities of certain metals or their salts, with polyfluorinated primary alcohols with the formation of phosphorylation products [bis(polyfluoroalkyl)(-polyfluoroalkylbenzyl)phosphates] exclusively.For previous communication, see [1].Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1660–1664, July, 1989.
