Low-temperature anomalies in the magnetoelectric properties of amorphous gallium antimonide
Demishev S. V. , Kosichkin Yu. V., Lyapin A. G., Sluchanko N. E.
Anomalies have been found in the electrical and magnetic properties of a mixture of amorphous and crystalline phases of gallium antimonide at low temperatures. These anomalies apparently stem from a superconductivity of an exciton nature. The superconducting features can be traced up to Τ ~100 К.
