Popis:	Nuclear magnetic resonance spin-echo technique was used on naturally abundant 57 Fe isotope to determine the thermal behavior of the local magnetic field in Ba 3 Co 2 Fe 24 O 41 hexagonal ferrite in the temperature range 4.2–320 K. Comparing to the ten sites known from crystallographic studies, signals from seven interstitial sites were detected. The results show that the local magnetic field in three sublattices decreases much more slowly than the macroscopic magnetization.
