摘要：

Magnetic glass-ceramic composites based on lanthanum-strontium manganite are obtained by thermal treatment of glass of the nominal composition La0.7Sr0.3MnO3 + SrSiO3 at 900-1200 degrees C. At a magnetic field strength of 720 kA/m, the samples are characterized by a magnetization up to 18.6 A/(m(2) kg). The obtained composites possess magnetoresistive properties. At 77 K and magnetic field strength 160 kA/m, the magnitude of the negative magnetoresistance is 2-6.5%.
