By means of $$^{27}$$Al NMR studies, we have investigated magnetic excitations and the hybridization effect between Pr 4$$f$$ and conduction electrons in a pair of cubic compounds Pr$$Tr$$$$_2$$Al$$_{20}$$ ($$Tr$$=Ti, V). From Knight shift measurements we have evaluated comparative strengths for the $$c$$-$$f$$ hybridization effect in these compounds and confirm a definite increase of hybridization on replacing Ti with V. Analysis of the spin-lattice relaxation rate $$1/T_1$$ reveals that the spectral width of magnetic fluctuations in crystalline electric field excited states is strongly temperature dependent. This result indicates that magnetic fluctuations are dominated by the strong $$c$$-$$f$$ exchange coupling at high temperatures and thus is nicely consistent with the Kondo picture that features ln$$T$$ dependence of resistivity over the same temperature region.

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$$times10^6$$ to 2$$times10^8$$ 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$$^2cdot$$mol.
