Half-metal is a term used in condensed matter physics and materials science to describe a class of materials that exhibit both metallic and insulating properties depending on the direction of electron spin. In simple terms, half-metals are materials that behave as conductors for one spin orientation (usually called "spin-up") while acting as insulators for the opposite spin orientation (usually called "spin-down").
