The NQR experiment under the zero field of ferromagnetic compound UGa was conducted. The experiment was conducted by paramagnetism and a ferromagnetic phase. Since Ga cores are I=3/2, a Ga-NQR resonance line is set to one in a paramagnetic phase. On the other hand, in the state of ferromagnetic order, division of a resonance line occurs by an internal magnetic field. The spectrum of a ferromagnetic order state was analyzed and temperature dependence of the internal magnetic field in Ga site was determined. With this compound, the resonance magnetism X-line scattering experiment of Ga orbit is conducted, and temperature dependence of that scattered intensity is measured. Therefore, the relation between an internal magnetic field and scattered intensity became clear. It argues also about the origin to the resonance magnetism X-line scattered intensity of Ga orbit.

Spin-orbit interaction leads to two competitive interactions, i.e., anisotropic exchange and anti-symmetric exchange interactions. Similarly, surface Rashba spin-orbit interaction gives rise to two effects in ferromagnets: one is prefer to the in-plane magnetic anisotropy while the other yields to the perpendicular magnetic anisotropy, and whether which is dominant depends on the electronic structure of ferromagnets. For the ultra-thin ferromagnetic layers, in particular, the surface Rashba spin-orbit interaction can be controlled by external electric fields and thus it is interesting to investigate electric field dependence of such a magnetic anisotropy. We present this new mechanism of perpendicular magnetic anisotropy.

Plasma size and power scalings of heat transport in ion temperature gradient driven turbulence are studied using the gyrokinetic full-f Eulerian code GT5D. Through systematic scans of heating power, the power degradation of confinement in L-mode plasmas is successfully recovered based on a first principle model for the first time. It is found that when heating power is scaled with plasma sizes, the power degradation of confinement leads to a Bohm scaling for large deveices, where conventional gyrokinetic delta-f codes asymptotically give a gyro-Bohm scaling.

We observed remarkable crystalline electric field (CEF) excitation in neutron inelastic scattering of UPdAl, indicative of the localized character of 5 electrons. The valence state is found to be U
with 5 configuration by CEF analysis of our data. On the other hand, the trivalent state was reported in AmPdAl and PuPdAl. NpPdAl shows intermediate valence between 3+ and 4+ reported by the effective moment, LDA calculation, and the large isomer shift of M
ssbauer spectra from trivalent state. We conclude that the valence instability is strongly related to the heavy fermion superconductivity in NpPdAl.

Recently, we proposed the multiple GPU computing with the common uni eddevice architecture (CUDA) for the Swendsen-Wang (SW) multi-cluster algorithm of two-dimensional (2D) q-state Potts model. In this speech, we propose the refined multiple GPU computing for the SW multi-cluster algorithm. By reducing the data traffic and the number of iterations in the inter-GPU calculation, we realize the more effective SW multi-cluster algorithm with multiple GPUs.

It is considered that not only thermal process but also non-thermal process named Spallation plays an important role on femtosecond laser ablation processes. However, few experimental results, which support the non-thermal process, have been reported. We succeeded in observing an experimental evidence of the spallation process on fused silica using time-resolved reflectivity.
