Research Abstract

The long-standing problems of the so-called hidden order in Uru_2Si_2 and characterization of the superconducting order parameter of Upt_3 have been studied extensively in this project. New cage materials including Pr have been synthesized and multi-pole ordering and superconductivity have been discovered. Epitaxial growth of several heavy Fermion materials with super-lattice structures has been made successfully for the first time, which leads to a new avenue to approach the problem of dimensionality of heavy Fermion superconductors.
