- Abstract
Superconductivity in polycrystalline FeTeSe was enhanced by heating in alcoholic beverages. We found that part of the excess Fe was deintercalated from the interlayer sites by the treatment and the shielding volume fractions were increased with the reduction of excess Fe content in sample. This behavior is similar to the case of FeTeS. Thus the technique of alcoholic beverage treatment can be applied generally to the Fe-chalcogenide superconductors.
