Magnetic properties of (SrFe12O19)x(CaCu3Ti4O12)1–x composites
New composite materials (SrFe 12 O 19 ) x (CaCu 3 Ti 4 O 12 ) 1– x ( x = 0, 0.05, 1) have been synthesized. Their magnetic properties are studied in the temperature range 5–300 K using the magnetic resonance and magnetometry methods. It is found that strontium hexaferrite microinclusions in the (SrF...
