Study of hybridization gap formation in a single crystal of the heavy-Fermion superconductor: CeCoSi3
Abstract: The solution of the Anderson lattice model (ALM) leads to two renormalized bands near EF with an energy gap due to hybridization between the 4f- and conduction electrons. The scattering across this hybridization gap has an energy scale equal to the Kondo temperature and is highly Q-dependent. In inelastic neutron scattering (INS) one expects the strongest intensity for the interband scattering at the indirect threshold near the zone boundary, where the weight is dominated by the 4f-electrons, while the weak scattering for the direct gap near Q=0. The measured INS in single crystals of YbAl3, CePd3 and CeIn1Sn3 agrees with the prediction of ALM. Recently we have investigated a powder sample of CeCoSi3 on HET and found a strong inelastic peak, near ~80-90 meV. Here we propose to investigate a single crystal of CeCoSi3 using the MERLIN spectrometer to test the predictions of the ALM.
