Investigation of giant crystal electric field (CEF) splitting in CeIr3Si2
CeIr3Si2 exhibits highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall CEF splitting of the J=5/2 ground multiplet of... -
Study of hybridization gap formation in a single crystal of the heavy-Fermion...
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... -
Study of hybridization gap and insulator-metal transition in caged compounds ...
Heavy fermion compounds with a small energy gap opening in the strongly hybridised 4f-band at EF are currently under intensive investigations. Recently some of us have...
