| Popis: | The paramagnetic g -value and linewidth of Nd 0.5 Sr 0.5 MnO 5 single crystal show the presence of spin clusters in the paramagnetic state. The anisotropy field splits the spectra below 250 K ( T C ). An A-type antiferromagnetic phase ( T N ∼ 225 K) is found to coexist with the ferromagnetic phase down to the charge ordering temperature of 150 K, at which a transition takes place also to a CE-type antiferromagnetic state. |
