Probing the mechanism of thermoelectric enhancement in Kondo insulator YbB12 ...
We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial... -
Two Kondo scales and crystal-field excitations in CeRuSn
At room temperature the ternary stannide CeRuSn crystallizes with a super structure of the monoclinic CeCoAl-type structure. Charge ordering produces a doubling of the unit cell... -
Neutron and muSR study of CePtSi: Non-Fermi liquid behaviour due to avoided m...
Previous studies have pointed to a heavy-electron state in CePtSi with a strongly enhanced electronic specific heat. We have explored the heat capacity, susceptibility and... -
Resonant Spin Excitation in Single Crystal of Ba0.8K0.2Fe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...
