Magnetic properties of dilute Al-REM alloys in liquid and amorphous states

Magnetic susceptibility of dilute Al-Ce and Al-Dy alloys is investigated in wide temperature and field ranges including liquid and amorphous phases. The abnormal behavior of susceptibilit y above melting point of Al 2R compound is discovered. The concentration curves (χ vs %REM) have oscillating shape similar in solid and liquid states. The existence of Al2R quasimoleculars is highly probable in these alloys and their destruction starts only above melting point of Al 2R compound. Magnetic properties of the alloys depend on behavior of such quasimoleculars - creation of chains, nets etc. The estimation of some parameters for such chains and nets is given.
