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... -
Magnetic and Quadrupolar Excitations in UPd3
UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal... -
Inelastic neutron scattering investigations of the high temperature phase tra...
Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at... -
SR study near the ferromagnetic quantum critical point in CePd1-xRhx ...
Rcently the NFL behaviour near an antiferromagnetic quantum critical point (AFQCP) has been investigated extensively. Very recently, we have investigated, for the first time,... -
Spin dynamics of Ce in the Noncentrosymmetric Heavy-Fermion Superconductors C...
In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have... -
Investigation of the field induced magnetic ordering in the spin gap compound...
Our neutron study on YbAl3C3 reveals the presence of two well defined magnetic excitations at 1.5 and 3 meV at 4 K due to spin-dimer formation. Interestingly the specific heat... -
STUDY OF HYBRIDIZATION GAP IN THE FILLED SKUTTERUDITE COMPOUND: CeOs4As12
We have recently investigated a hybridization gap in Kondo systems using HET and several papers along with a review have been published. Our study shows a universal scaling... -
Lattice dynamics study of filled-skutterudite compounds: RPt4Ge12 (R=Ba, La a...
The appearance of non-dispersive Einstein (¿rattling¿) modes, known as the phonon-glass paradigm in filled-skutterudite compounds, has been postulated as an origin of the high... -
Investigation of the Bose-Einstein condensation (BEC) of magnons in YbAl3C3 u...
Our neutron scattering study on YbAl3C3 clearly reveals the presence of two well defined magnetic excitations at 1.5 and 3 meV at 4 K due to spin-dimer formation. Interestingly,... -
Investigation of short range magnetic correlations in CeIr3Si2 using SR
CeIr3Si2 reveals highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall crystal electric field (CEF) splitting of the J=5/2... -
Inelastic neutron scattering study of spin gap formation in two forms of BaRuO3
Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through... -
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...
