Outline of Final Research Achievements

With the search for new material seeds characterized by the behavior of 5d electrons, we aimed to improve half-metal functionality on the background of the extended electron orbitals, strong spin-orbit interaction, and remarkable relativistic effects inherent to 5d electrons. As a result, although it did not reach to the synthesis of the half metal of the oxide over 600 K which was aimed at, the new substance synthesized in the process of research showed unique physical properties and we published the results through the conference presentation and the paper presentation.
