The effective magnetic momentum peff of Gd-impurities in the Pb1-xSnxTe(Gd) crystals as a function of crystal composition x with 0 < x < 0.25 is studied.It is shown that with the increase in tin con- tent in the crystals from 0 to 0.15, p(Gd) increases slowly from 37 to 43.Then p2eff(Gd) increases abruptly to 63 value when x = 0.16 ± 0.01.For sub- sequent increase x > 0 . 1 7 p 2 e f f ( G d ) r e ma i n s c o n s t a n t a t 6 3 .P o s s i b l e r e a s o n s of observed changes of peff (Gd) and possible mechanisms of in fluence of the Pb 1x Snx Te crystal field on the effective magnetic momentum value of Gd -impurities in the crystals under study are analysed.

Study of the Gd Impurity Influence on the Defect Structure of Pb1-xSnxTe Crystals by Means of119Sn M�ssbauer Spectroscopy

Pb1—xSnxTe:Gd solid solutions grown from the melt by the Bridgman method and doped during growth with Gd have been investigated by means of 119Sn Mössbauer spectroscopy. It was found that the doping had a considerable influence on the Mössbauer spectrum linewidth Γ. The observed changes in Γ were explained by changes in the local surrounding of Sn nuclei and by electric field gradient rise caused by Te vacancies. It was concluded that Gd doping during the growth of the investigated solid solution crystals caused a decrease in the concentration of Te vacancies.

Specific magnetic properties of the Eu-doped pbte single crystals

Journal of Physical Studies (2012)

The magnetization M under temperature 1.72 K in the range of magnetic field B 0-5 T and the magnetic susceptibility (MS) χ under magnetic field 0.1 T in the temperature range 1.7-400 K of the powder and crystal PbTe:Eu samples fabricated from the bulk and surface layers of the doped ingots grown from the melt by the Bridgman method are investigated.Specific magnetic properties in the Eu-doped PbTe single crystals are revealed: (i) the strong differences between the magnetization and MS of the surface and bulk of the PbTe:Eu doped ingots; (ii) strong paramagnetism of the surface layers practically independent of T in the temperature range over 30 K; (iii) the principal discrepancies between the temperature dependences of MS of the crystal matrix of powder and crystal doped samples.Possible mechanisms of the appearance of the mentioned peculiarities of the magnetic properties of different powder and crystal samples are analyzed.
