Abstract
The phase relations, mechanism of phase formation, crystal structures, physical properties of novel compounds in the Ce–Zn–Si system were investigated.
Highlights
Ternary compounds Ce–T–Si (T is one of the late transition metals) have been known for their interesting physical properties, such as heavy fermion and unconventional superconductivity,[1,2] Kondo-behaviour and quantum criticalities,[3] intermediate valency,[4] thermoelectric features,[5] etc
A few investigations were already concerned with the Ce–Zn–Si system
Phase equilibria for the Ce–Zn–Si system have been derived at 800 C by Malik et al.[8] and revealed the existence of 4 ternary compounds, labeled as s1 to s4
Summary
Ternary compounds Ce–T–Si (T is one of the late transition metals) have been known for their interesting physical properties, such as heavy fermion and unconventional superconductivity,[1,2] Kondo-behaviour and quantum criticalities,[3] intermediate valency,[4] thermoelectric features,[5] etc. The high vapor pressure of these metals complicates sample preparation, and requires careful control of compositions. Kido et al.[7] reported paramagnetism and metallic behavior of REZnSi compounds (RE 1⁄4 Ce, Nd, Sm, Gd, Tb, Ho) in the temperature range of 77–300 K. Phase equilibria for the Ce–Zn–Si system have been derived at 800 C by Malik et al.[8] and revealed the existence of 4 ternary compounds, labeled as s1 to s4.
