Kolejny czwarty zeszyt Prac Fizycznych składa się z dwu części. Część I zawiera prace naukowe zespołu metodycznego i teoretycznego. W części II prezentowane są prace związane z tematyką zespołu doświadczalnego. Członkowie ...

The magnetic shielding of [23]Na nuclei in NaNO[3], NaClO[3], NaBrO[3] was investigated theoretically and experimentally. The theory of the magnetic shielding based on the perturbation theory approach of Ramsey was used. ...

The method of hot pressing permits to obtain the ceramics of high density. It consist in simulate neons application of high temperature and pressure on charge made of pressed powder. The authors elaborated several devices ...

This article contains analysis and comparison of different methods of the cross section calculation for the magnetic scattering of thermal neutrons by paramagnetic ion (Trammell method, Lovesey method, Stassis method, ...

Superiority of PZT ceramic (modificated) obtained in Science - Research Institut of Physics Rostov - State University (USSR) in comparison with commercial Soviet and American analogues, have been presented in this paper. ...

This paper deals with the structural data of all known magnetic compounds of ilmenite structure. The parameters of the crystallographic and magnetic rhombohedral cells, also for the reciprocal lattice are compared. The ...

Some thoughts concerning the role of theoretical physics in educating the teachers of physics are presented by the authors of the paper. They evaluate the importance of theoretical physics in the university syllabi and ...

A general definition of symmetries of gauge fields is proposed and a method developed for constructing symmetric fields for an arbitrary gauge group. This method was used to find SU(2) (and SU(3)) Yang-Mills fields ...

The relativistic correction is derived for the general formula of the cross section for magnetic scattering of thermal neutrons by paramagnetic ion, obtained by Lovesey for nonrelativistic approximation.

The electric properties and specially influence of defects on electrical conductivity are presented for modified PZT ceramics. The spectr of energie for oxides perovskite type A[2+]B[4+]O[3] is shown. The influence of ...
