Abstract
Single crystals of the Er2PdSi3 intermetallic compound melting congruently at 1648Â âC, were grown by a floating zone method with radiation heating. The control of oxygen content was the key factor to avoid oxide precipitates, which can affect effective grain selection in the crystal growth process. Crystals grown at velocities of 5Â mm/h with a preferred direction close to (1Â 0Â 0) with inclination angles of about 12â against the rod axis show very distinct facets at the rod surface. The crystals are Pd-depleted and Si-rich with respect to the nominal Er2PdSi3 stoichiometry, but exhibit inferior element segregation. Measurements on oriented single crystalline samples revealed antiferromagnetic ordering below 7Â K, a magnetic easy axis parallel to the (0Â 0Â 1) axis of the AlB2-type hexagonal unit cell, and anisotropic electric properties.
