A high performance rare earth-transition metal magnetostrictive material with increased impurities having the formula (R x1R x2...R x11)1(M y1M y2...M y6)z 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 <= xl <= 1, 0 <= x2 <= 1...0 <= x11 <= 1 and where x1 + x2 +...+ x11 = 1. Each M is selected from the group of elements consisting of iron, manganese, cobalt, nickel, aluminum and silicon, where 0 <= y1 <= 1, 0< y2 <= 1...0 <= y6 <= 1, where y1 + y2 +...+ y6 = 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.

L'invention concerne un type de matériau magnétorestrictif en métal de transition des terres rares haute performance à impuretés accrues, représenté par la formule (R¿x1?R¿x2?...R¿x11?)1(M¿y1?My2 M¿y6?)¿z?. Chaque R appartient au groupe suivant: lanthane, cérium, praséodyme, néodyme, samarium, gadolinium, terbium, dysprosium, holmium, erbium et yttrium, sachant que 0 <= x1 <= 1, 0 <= x2 <= 1...<= x11 <= 1 et que x1 + x2 +...+ x11 = 1. Chaque M appartient au groupe suivant : fer, manganèse, cobalt, nickel, aluminium et silicium, sachant que 0 <= y1 <= 1, 0 <= y2 <= 1...<= y6 <= 1, avec y1 + y2 +...y6 = 1 et 1,8 <= Z <=2,1. Le matériau comporte des impuretés d'oxygène, d'azote et de carbone. Les impuretés d'oxygène ont un pourcentage atomique compris entre 6 011 et 34 000 parties par million. Les impuretés d'azote ont un pourcentage atomique compris entre 575 et 4 400 parties par million. Les impuretés de carbone ont un pourcentage atomique compris entre 939 et 21 000 parties par million. Le matériau offre une performance acceptable en matière de contrainte à magnétorestriction, pour un coût réduit.
