Abstract
In this proposal we show evidences of the superconductivity possibility in a new serie of boride materials which can crystallize in a FeB prototype structure with general chemical formula Ta1-xZrxB and Ta1-xTixB. This possibility are sustained by superconductivity behavior in another member of Ta1-xHfxB stoichiometry, which exhibit superconducting behavior with signature of multi band. Pr…
