Phase diagram studies on Er2PdSi3 and ErPd2Si2 intermetallic compounds

Crystal growth of the Pr2PdSi3 intermetallic compound

“…The reason for the accumulation of Pd in the melt is the slightly Pd-depleted growing crystal as described below. The continuous composition shift of the floating zone implies a gradual slope down of the operating temperature of the crystallization, which seemingly originates from the decreasing liquidus temperature with rising Pd concentration similar to the Er-Pd-Si phase diagram, which has been studied recently [18].…”

Self-flux growth of large EuCu2Si2 single crystals

“…The diversity in the magnetic properties of single crystals from different preparation routes is assumed to result from small differences in composition, lattice parameters and chemical disorder, which are characteristic for the class of RT 2 Si 2 intermetallics. For example a wide homogeneity range was previously verified in the ErPd 2 Si 2 compound [15]. Only the EuCu 2 Si 2 crystals prepared by the FZ method display typical behavior attributed to valence fluctuations in Eu, which is known from stoichiometric polycrystalline samples [3,4].…”

Crystal growth of rare earth-transition metal borocarbides and silicides

“…A similar congruent melting behavior of ErPd 2 Si 2 at T m ¼ 1420 1C was recently found, which is representative for the class of RPd 2 Si 2 compounds. However, different from the R 2 PdSi 3 compounds ErPd 2Àd Si 2+d exhibits a relatively extended homogeneity range of dp0.3 which can give rise to a crucial dependence of physical properties on growth conditions [32].…”

“…A typical Er-Pd-Si phase diagram section is shown in Fig. 3 [32]. These compounds can directly grow from the stoichiometric melt and a composition difference in FZ only occurs if the actual crystal composition differs from that of the maximum melt temperature (dystectic point).…”
