|Magnetic properties and crystallization behavior of Al-Co-Ce(Dy) amorphous ribbons / V. Sidorov, V. Mikhailov, P. Svec [и др.] // Journal of magnetism and magnetic materials. — 2015. — Vol. 395. — P. 324-328.
|Magnetic and electric properties as well as the structure (by Vrays) and DSC of Al91Co2Ce7 and Al89Co5Dy6 alloys in amorphous and crystalline states are studied. For both ribbons crystallization goes into two stages. In case of Al91Co2Ce7 composition it starts with the formation of Al nanoparticles; after that Al11Ce3 and Al9Co2 compounds appear. For Al89Co5Dy6 ribbon the situation is vice versa - the crystallization of Al3Dy compound Lakes place at the first stage vvhereas crystallization of aluminum matrix arises at the second stage only. The effective magnetic moments per Cc (Dy) atoms were found to be smaller than for R3+ ions suggesting that rare-earth atoms create directed bonds with aluminum atoms. (C) 2015 Elsevier B.V.
