Abstract
We have succeeded in growing a high-quality single crystal of a non-4 f reference compound YCu 2 Si 2 for a heavy-fermion superconductor CeCu 2 Si 2 , and observed the de Haas–van Alphen (dHvA) oscillation. The detected dHvA branches in YCu 2 Si 2 indicate that the Fermi surfaces are multiply connected, and the dHvA frequencies are in the range from 9×10 6 to 2×10 8 Oe. These dHvA branches are found to be well explained by the results of energy band calculations. The corresponding cyclotron masses are light, ranging from 0.4 to 1.5 m 0 , and are consistent with the electronic specific heat coefficient of 2.2 mJ/(K 2 ·mol).
