In Situ Study of Atomic Clustering in Fe-19 Ga Type Alloy / I.S.Golovin, A.M.Balagurov, [et al.] // Materials Letters [Electronic resource]. – 2024. – Vol. 375. – P. 137206. – URL: https://doi.org/10.1016/j.matlet.2024.137206. – Bibliogr.: 25.

The results of high-precision electro-resistivity measurements, *r(T), for Fe-18.5%Ga alloy over a wide temperature range are presented. An anomaly in the *r(T) temperature behavior is detected and it is proved that it correlates well with the change in the unit cell lattice parameter of the alloy and with the results obtained from measuring magnetization, dilatometry and positron annihilation. From the neutron diffraction data, it follows that the detected anomaly is associated with the formation of a cluster-like microstructure of the alloy: in the structurally disordered A2 matrix, regions with partially ordered D0&sub(3) phase are formed. Interpretation of this non-monotonic behaviour of *r(T) is discussed.
