What is Gauss? Gauss is a unit of measurement used to describe both the coercivity of a magnet and its saturation magnetization. Basically, it describes how strong the magnetic fields are extending from the magnet and how strong of a magnetic field it would take to de-magnetize the magnet. The name comes from the mathematician physicist Carl Freidrich Gauss.
Gadolinium is a chemical element with symbol Gd and atomic number 64. It is a silvery-white, malleable and ductile rare-earth metal.It is found in nature only in combined (salt) form. Gadolinium was first detected spectroscopically in 1880 by de Marignac who separated its oxide and is credited with its discovery.adolinium as a phosphor is also used in other imaging. In X-ray systems, gadolinium is contained in the phosphor layer, suspended in a polymer matrix at the detector. Terbium-doped gadolinium oxysulfide (Gd 2 O 2 S: Tb) at the phosphor layer converts the X-rays released from the source into light.
