SEMI-METALLIC FERROMAGNETIC OR FERRIMAGNETIC MATERIAL, AND DEVICE EMPLOYING SUCH MATERIAL

摘要

Title: Semi-metallic ferromagnetic or ferrimagnetic material, and device employing such material. of the disclosure: A material built up from a plurality of elements, having a crystal structure in which the occupation of the positions in the crystal lattice by the different elements, and the choice of these elements for these positions are such that, in one direction of magnetic polarization, the material exhibits all properties of a metal as regards the transport of electrons with a given direction of spin, while for electrons of opposite magnetic spin the material exhibits all properties of a semi-conductive material or an insulator.
