Abstract
A high performance rare earth-transition metal magnetostrictive material with increased impurities having the formula (R,R,. . . R,),(M,M,. . . M,),is provided. Each R is selected from the group of elements consisting of lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, erbium and yttrium, where 0≦x,≦1, 0≦x,≦1 . . . 0≦x,≦1 and where x,+x,+ . . . +x,=1. Each M is selected from the group of elements consisting of iron, manganese, cobalt, nickel, aluminum and silicon, where 0≦y,≦1, 0≦y,≦1 . . . 0≦y,≦1, where y,+y,+ . . . +y,=1 and where 1.8≦z≦2.1. The material has oxygen impurities, nitrogen impurities and carbon impurities. The oxygen impurities having an atomic percent ranging from 6,011 to 34,000 parts per million. The nitrogen impurities having an atomic percent ranging from 575 to 4,400 parts per million. The carbon impurities having an atomic percent ranging from 939 to 21,000 parts per million. The material exhibits acceptable magnetostrictive strain performance at a reduced cost.
