Kondo effect in CeX (X=S, Se, Te) studied by electrical resistivity under high pressure
We have measured the electrical resistivity of cerium monochalcogenices, CeS,
CeSe, and CeTe, under high pressures up to 8 GPa. Pressure dependences of the
antiferromagnetic ordering temperature , crystal field splitting, and
the anomaly of the Kondo effect have been studied to cover the whole
region from the magnetic ordering regime at low pressure to the Fermi liquid
regime at high pressure. initially increases with increasing pressure,
and starts to decrease at high pressure as expected from the Doniach's diagram.
Simultaneously, the behavior in the resistivity is enhanced, indicating
the enhancement of the Kondo effect by pressure. It is also characteristic in
CeX that the crystal field splitting rapidly decreases at a common rate
of K/GPa. This leads to the increase in the degeneracy of the state
and further enhancement of the Kondo effect. It is shown that the pressure
dependent degeneracy of the state is a key factor to understand the
pressure dependence of , Kondo effect, magnetoresistance, and the peak
structure in the temperature dependence of resistivity.Comment: 9 pages, 5 figures, accepted for publication in J. Phys. Soc. Jp
Anti-deuteron beam study at J-PARC HEF K1.8 beam line
We performed a beam study at the K1.8 beam line of J-PARC
Hadron Experimental Facility. 1.8 GeV/ beam yield was
measured to be 0.30 0.04 counts/spill for 30 GeV 70
protons/spill irradiated on a 66 mm thick of gold target with the vertical slit
opening widths of 2.2 mm, 5 mm and 5 mm for intermediate focus (IFV), mass slit
1 (MS1) and 2 (MS2), respectively. Corresponding beam yield is
roughly estimated to be 0.3 Mcounts/spill for the same slit condition.
Then, the production ratio at extraction angle of 6
degrees is estimated to be . This is the first time measurement
of the beam yield and production
ratio at J-PARC. Further beam line tuning may increase the beam
yield.Comment: 13 pages, 9 figures, J-PARC HEF K1.8 beam line group technical repor
