Czochralski Method for Crystal Growth οf Reactive Intermetallics

Czochralski method of crystallization allows obtaining single crystals of many intermetallic compounds. New series $Gd_7Ni_xPd_{3-x}$ (x=2, 3) intermetallics was grown by the modified Czochralski method using a levitated melt in protective argon atmosphere. Preliminary studies of magnetic properties have shown that all crystals of the series order ferromagnetically. It was found that $Gd_7Ni_2Pd$ shows magnetic transition to the ferromagnetic state at 225 K while $Gd_7Ni_3$ orders at 145 K.
