Outline Activities
1. Safety management for radioisotope and nuclear materials:
As a member of Central Institute of Radioisotope Science and Safety Management and Director of the nuclear Material Safety Management Department, main role is to protect users from unnecessary exposure (external and/or internal) from the radioisotope and nuclear materials and keep the facility in safe. To establish a effective rule and guidelines for the use of the facility is important for users. Education for users (researchers and students) related to radiological technology according to the rules and guidelines are also important task.
2. Study of electronic properties on rare-earth and actinide compounds:
Rare-earth and actinide compounds show rich variety of electronic properties such as magnetism, superconductivity, multipole ordering, quantum critical phenomena. It is widely recognized that pressure technique is a powerful tool, where the inter atomic distances and various interactions can be tuned precisely, to investigate electronic properties of condensed matter. With the combination of high quality single crystal growth and high pressure techniques, I am investigating new interesting compounds and new functional materials for basic and/or applied research.

The measurements on a single-phased sample of YbCo2 bring no evidence of magnetic ordering down to 0.3 K in a zero magnetic field. The manifestations of low Kondo temperature are observed. The specific heat value divided by temperature, C/T, keeps increasing logarithmically beyond 7 J/mol K2 with decreasing temperature down to 0.3 K without no sign of magnetic ordering, suggesting a very large electronic specific heat. Analysis of the magnetic specific heat indicates that the large portion of the low-temperature specific heat is not explained simply by the low Kondo temperature but is due to the strong intersite magnetic correlation in both the 3d and 4f electrons. Temperature-dependent measurements under static magnetic fields up to 7 T are carried out, which show the evolution of field-induced transition above 2 T. The transition temperature increases with increasing field, pointing to a ferromagnetic character. The extrapolation of the transition temperature to zero field suggests that YbCo2 is in the very proximity of the quantum critical point. These results indicate that in the unique case of YbCo2, the itinerant electron magnetism of Co 3d-electrons and the Kondo effect within the vicinity of quantum criticality of Yb 4f-local moments can both play a role.. |

RPt3Al5 crystalizes in the CePt3Al5-type orthorhombic structure where R atoms form 1-dimensional chains along the b-axis. LaPt3Al5 shows superconductivity below 0.4 K, while others show magnetic ordering. CePt3Al5 orders antiferromagnetically below TN = 1.2 K with spontaneous moment and shows successive magnetic transition at Tm = 0.9 K. The nearly divalent antiferromagnet EuPt3Al5 indicates an unusual valence cross-over behavior into the nearly trivalent state under high pressure of 9 GPa. It is also found that most of RPt3Al5 orders antiferromagnetically and, in some cases, shows characteristic features in magnetic susceptibility, where the broad maximum appears slightly above TN, reflecting the low-dimensional nature.. |
