“…The comparison of SEM, XRD, TEM, SAED, X-ray absorption near-edge structure (XANES), extended X-ray absorption ne structure (EXAFS), and Möss-bauer data for the studied samples, presented in [3,4,6], has allowed to make the following conclusions concerning their phase structure. Discussion of the obtained σ(x, T ) dependences for the studied samples, belonging to dierent regions A, B, and C in Fig.…”
