The main application of terbium metal : manufacture of phosphors, lasers, magnetic and thermoelectric materials, computer semiconductor parts, magnetostrictive alloys. Alloy Fe-Tb today is the best magnetostrictive material used for the production of high-power mechanical drives (for example, telescopes), for ultrasonic emitters. In addition, newer terbium compounds are being introduced, for example, a single crystal of Tb titanate, which has an enormous magnetostriction.

Swedish chemist Carl Gustaf Mosander discovered terbium metal as a chemical element in 1843. He detected it as an impurity in yttrium oxide, Y2O3. Yttrium and terbium are named after the village of Ytterby in Sweden. Terbium was not isolated in pure form until the advent of ion exchange techniques. Terbium is a silvery-white rare earth metal that is malleable, ductile and soft enough to be cut with a knife. It is relatively stable in air compared to the earlier, more reactive lanthanides in the first half of the lanthanide series.
Terbium has a simple ferromagnetic ordering at temperatures below 219 K. Above 219 K, it turns into a helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel, and oriented at a fixed angle to the moments of adjacent layers. This unusual antiferromagnetism transforms into a disordered paramagnetic state at 230 K.
