V.Е. Rode, S.А. Sorokina, L.А. Arkhipkin, and Е.Yu. Sumarokov
Measurements are reported of the thermal expansion coefficient of amorphous invar alloys containing 15-20 at.% of Fe in the temperature range 4.2 -300 К. The magnetic contribution to thermal expansion is estimated and the results are interpreted in terms of the coexistence of ferro - and antiferromagnetic components in the amorphous alloy.

Oscillations have been detected on the Hall voltage in $p-Bi_2Te_3$, single crystals, which have the form of а series of plateaus. The quantization of the Hall effect is due to the staЫlization of the Fermi level in the impurity band lying above the top of the heavy-hole band in $Bi_2Te_3\langle Sn \rangle$.
