- Abstract
New composite materials (SrFeO)(CaCuTiO) ( 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 (SrFeO)(CaCuTiO) composite 'magnetize' CaCuTiO at temperatures from 300 to 200 K, forming a ferrimagnetic particle near the SrFeO 'core.' The magnetic resonance line below 200 K splits into two lines corresponding to SrFeO and CaCuTiO. The core effect decoration is manifested in the increase in the Curie-Weiss temperature from 25 K in CaCuTiO without the doping ceramics to 80 K in the composite with 5% of SrFeO.
