Opisano metodę pomiaru ogromnej magnetostrykcji związków międzymetalicznych typu ciężka ziemia rzadka - żelazo przy użyciu tensometrów jako mierników odkształcenia. Przedstawiono układ pomiarowy oraz przebieg pomiaru. Podano wyniki pomiarów ogromnej magnetostrykcji otrzymane dla związków typu ciężka ziemia rzadka - żelazo posiadających strukturę krystaliczną typu MgCu2.
The method described in this work is the strain gauge method used to measure huge magnetostriction of the heavy rare earth - iron intermetallics. The measuring system and the procedure of measurement are presented in this work. The results of huge magnetostriction determined for the heavy rare earth-iron compounds with the MgCu2 - type crystal structure are shown.
