Abstract
This work proposal is about the research of promising new materials for superconductivity that crystallize in YbMo2Al4 prototype. Preliminary results presented in this proposal, show unambiguously that two members of this family with HfV2Ga4 and ScV2Ga4 compositions are new superconductors with critical temperatures of 4.0 K and 3.0 K respectively. These materials exhibit strong signature…
