superconductive
"superconductive" in relation to materials (e.g. metals, alloys or compounds) means those which can lose all electrical resistance (i.e. which can attain infinite electrical conductivity and carry very large electrical currents without Joule heating); the superconductive state of a material is individually characterised by a 'critical temperature', a critical magnetic field, which is a function of temperature, and a critical current density which is a function of both magnetic field and temperature; Technical Note: 'Critical temperature' (also known as the transition temperature) of a specific "superconductive" material means the temperature at which the specific material loses all resistance to the flow of direct electrical current.
