Single-crystal iron-manganese sulfide FeXMn1-XS C whopping MAGNETOSTRICTION

摘要

FIELD: chemistry.;SUBSTANCE: invention can be used in microelectronics when designing magnetostrictive materials. The monocrystalline giant magnetostrictive iron-manganese sulphide Fe_xMn_1-xS, in which x=0.18; 0.27; 0.29, contains iron, manganese and sulphur, with the following ratio of components, respectively, wt %: iron - 11.53; 17.28; 18.55; manganese - 36.78; 36.75; 36.74; sulphur - 51.69; 45.97; 44.71.;EFFECT: invention enables to obtain monocrystalline iron-manganese sulphide having abrupt change of magnetic susceptibility in the region of magnetic transition and magnetostriction whose sign varies with temperature.;4 dwg, 2 tbl
