N2 - Half-metal is a class of the metallic ferromagnet having a 100% spin polarization. The conduction electrons of half-metals can only carry electrons with a particular spin orientation. Because of this, the current generation of half-metal is expected to be governed only by the particular conducting spin. However, the contribution of the opposite spin, on which the half-metal acts as an insulator, is often neglected. Here we theoretically study the contribution of this insulating spin on the spin transport in the half-metal, in comparison with the conducting spin. We found that the collective dynamic of the insulating spin is responsible for magnonic transport that in turns influence the spin current generation in the half-metal.
