Abstract
The electrical-resistance behavior of strontium is studied for various pressures from 250 up to 500 kbar and for temperatures from 2 to 300 K. Superconductivity has been observed in strontium for pressures higher than 350 kbar. The superconducting transition temperature varies from 3 to 4 K with being positive in the pressure range investigated. Superconductivity in Ba is also investigated for pressures from 200 to 400 kbar. for Ba becomes negative in this pressure range.
