DC Magnetization and Growth of Heavy-Fermion Superconductor CeCoIn$_{5 }$and CeIn$_{3}$ Crystal

The superconducting and magnetic state in heavy-fermion intermetallic compounds provides a promising realm of materials to study quantum critical behavior. Single crystals of the heavy-fermion superconductors CeCoIn$_{5 }$and CeIn$_{3 }$were$_{ }$ synthesized from the pure element using an excess of Indium. The material crystallizes in the body tetragonal space group P4/mmm structure of HoCoGa$_{5}$ and has alternating layers of CeIn$_{3}$ and CoIn$_{2}$. The details of the flux growth technique used to grow CeCoIn$_{5 }$and$_{ }$CeIn$_{3}$, and the result of DC magnetization and transport measurements performed in the temperature range 1.9K to 100K will be reported.
