At low temperatures, these compounds exhibit spin-glass properties with freezing temperatures Tf = 26 and 33 K, respectively, and typical features in the magnetic hysteresis and in the dependences of the real part of the dynamic magnetic susceptibility on temperature and ac magnetic field frequency. Above Tf, the static magnetic susceptibility of the samples studied depends on the applied magnetic field, which is tentatively assigned to the presence of metallic cobalt and/or yttrium orthoferrite YFeO3 introduced in the course of sample preparation Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Korolev, A.
