Abstract:
The magnetoresistance of single crystals of ErGa2, Tb3Co and NdCu2 compounds has been studied in the regions of the field-induced spin-flip transitions. An anomalous increase was found in the electrical resistivity in the intermediate state where the magnetic phases with the different magnetic structures coexist. A theoretical model to explain this anomaly is proposed. The peaks of the electrical resistivity in this model are connected with the s electron reflection from the potential barrier at the interphase boundary separating the phases with different magnetic structures. This effect is the magnetic analogy of so-called Andreev's reflection in superconductors. © 1993.
