Abstract
New ternary compounds having the formula EuTCu4 where T=Al, Pd and Ag have been synthesized. All these compounds are found to crystallize in the hexagonal CaCu5 type structure. Magnetization measurements reveal that these compounds are magnetically ordered with magnetic moments close to 7 μB. The Curie temperatures obtained from low field ac susceptibility measurements are 26K, 25K and 50K for T-Al, Pd and Ag respectively. 151Eu Mössbauer studies at room temperature show a large negative isomer shift relative to SmF3. A hyperfine split pattern is observed at 4.2K in all these compounds, indicating that Eu ion is present in a divalent state and is magnetically ordered.
