Аннотация:Magnetic glass-ceramic composites containing micron-sized particles of lanthanum strontium manganite in the matrix of borate-silicate phases were prepared by thermal treatment of amorphous samples of nominal composition 28La(2)O(3)-22SrO-25MnO (x) -17SiO(2)-8B(2)O(3)at 800-1150A degrees C. The samples obtained exhibit high magnetization up to 25 A m(2)/kg at a magnetic field strength of 720 kA/m. The relative magnetoresistance amounts to 17% at 77 K and a magnetic field strength of 160 kA/m.
