Parameters of chromium impurity band in Pb1-x-yGexCryTe alloys

Galvanomagnetic properties ( = 4.2 K, ≤ 8 T) of -Pb1-x-yGexCryTe alloys under variation of alloy composition ( x = 0.02-0.10, z = 0.01-0.03) and under pressure (P ≤ 17 kbar) have been investigated. Magnetic field dependences of the Hall coefficient H near the metal- insulator and insulator-m...
