“…On the other hand, this property can be used to distinguish between the different contributions to the magnetization, as has been elegantly shown, e.g., in the case of the mixed valence system HgSe:Fe. 10 There are two designs for the rotor depending on whether the sample is a solid or a liquid. In the case of a solid state sample the rotor is a hollow cylinder with the sample platform symmetrically dividing the wheel into two parts.…”

We describe the design and construction of a sensitive dc torque magnetometer suitable for liquid as well as solid state samples. It can be used from room temperature down to very low temperatures (mK range) in magnetic fields produced either by superconducting or resistive magnets, in particular in the high fields (B≈30 T) produced by Bitter and hybrid magnets. The highest resolution that we have attained so far is about 0.3 pNm, which is mainly the result of a symmetric design. In typical laboratory conditions (at B=10 T) this corresponds to a magnetization resolution of about 3×10−11 emu. Other features include modularity, linearity, feedback and forward bias capabilities, and an in situ calibration of the signal.

“…[49]. The magnetization study of Hg1-xFe xSe was performed by von Ortenberg et al [50], Wilamowski et al [51], Dybko et al [52] and Zeitler et al [53]. The very characteristic feature observed at low temperatures is the presence of de Haasvan Alphen oscillations superimposed on the magnetization curve.…”

The article reviews the physical properties of semimagnetic semiconductors of the type Hg1-x-yFexΑ Se1-xΒzVI 1 and Hg1-x-yFexMnySe. Optical, magnetooptical, transport and magnetotransport experiments showed that in Hg1-xFexSe substitutional iron forms a resonant donor state whose energy is superimposed on the conduction band continuum. Resulting anomalous properties of electron scattering rate, i.e. strong enhancement of electron mobility (or drop of Dingle temperature), which occur in Hg1-xFexSe at low temperatures in a certain Fe concentration range, are described. Next, theoretical models describing this anomalous reduction of the scattering rate are discussed. The description of thermomagnetic, optical, magnetooptical and magnetic properties of Hg1-xFe x Se, with emphasis on features originating from the peculiar iron level position in the band structure of Hg 1-xFexSe, conclude the first part of the present paper. In the second part the physical properties of the semiconducting alloys Hg1-x Mn x Se:Fe, Hg1-vCdvSe:Fe, Hg1-xΖnxSe:Fe, HgSe1-xTex:Fe and HgSe1-xSx:Fe are described. In particular, the dependence of the position of the Fe resonant donor state in the band structure on the crystal composition is discussed. The values of predicted Γ6 and Γ8 band offsets between HgSe and CdSe, HgTe, MnSe and ZnSe are given. The considerable attention is paid to the discussion of the m e c h a n i s m l i m i t i n g t h e e l e c t r o n m o b i l i t y i n t h e
