| Popis: | The 63,65Cu nuclear magnetic resonance (NMR) spectra have been obtained in the external magnetic field H0 = 11.7 T at the temperature range from 20 to 350 K and the static magnetic susceptibility, χ(T), has been measured in single-crystalline CuFeO2. The temperature dependences of the 63,65Cu NMR line shifts, K(T), and the magnetic susceptibility, χ(T), can be satisfactorily described by Curie–Weiss law at T > 60 K. It is worth noting that the behavior of K(T) and χ(T) is different below T = 60 K. The deviation of K(T) from the Curie–Weiss law indicates the short-range order at T |
