The structural (at T = 300 K) and magnetic properties of LaMnO3 + delta nanoceramic materials prepared by shock-wave loading have been investigated in the paramagnetic region. The samples contain a mixture of the orthorhombic and rhombohedral phases in different ratios. The Curie-Weiss law is satisfied in the temperature range T > 440 K > 2T (C), and magnetic polarons are generated in the vicinity of defects at temperatures in the range 300 K < T < 440 K. An increase in the con
