In half metals which have the metallic nature for one electron’s spin and the non-metallic nature for the other, the current can be completely spin polarized. However most half metals are inorganic systems and 3-dimensional systems. There have been some reports on 1-dimensional and 2-dimensional organic (or organometallic) half metals: graphene nanoribbon (GNR) under strong electric field, edge-modified zigzag GNR, hybrid BCN nanoribbons, and 1D organometallic half metals. The advantage of using organic materials as spin-based electronic (spintronic) devices is that the spin relaxation length and spin lifetime are considerably long because of weak spin-orbit and hyperfine interactions. In addition, organic materials are usually inexpensive light materials and would be candidates for flexible devices. Here, we discuss 2-dimensional organic half metal, 2,4,6-tri-(1,3,5-triazinyl)methyl radical polymer, which is a candidate of complete spin polarized carrier sources. It would be possible to achieve spontaneous magnetic ordering.
