Abstract

We have studied the single crystal growth and the physical properties of the UT₂Al₂₀ system. We have successfully grown UT₂Al₂₀ (T = Cr, Ti, W and Mo) using Al self flux and have characterized the crystals using electron probe microanalyzer (EPAM) and X-ray diffractometer. We have also measured their magnetic and electric properties. The ground states of UT₂Al₂₀ (T = Cr, Mo and W) are Pauli paramagnetic as is likely also in UTi₂Al₂₀. The effective masses of UCr₂Al₂₀ and UTi₂Al₂₀ are only weakly enhanced.
