Disorder of anisotropy is introduced into spin 1 2 quantum XXZ chains. This model, which is refered as the spin 1 2 ± J z chain, is studied by the quantum Monte Carlo method. It displays the critical phenomena of the x−y phase, though the critical

The electronic structure of ferromagnetic binary bcc Fe 0.98 Ni 0.02 and Fe 0.8 Ni 0.2 alloys are calculated by the KKR-CPA method using two charge neutrality conditions. The two charge neutrality conditions are considered to be satisfied by each sit

The boson tendency to clump deuterons in palladium, which is caused by an attractive force, supplies kinetic energy to deuterons moving toward the center of the cluster. On the other hand, repulsiv...

The phonon contribution to the resistive force acting on a moving dislocation is discussed, and an expression of the dislocation damping constant is obtained. The damping constant of a dislocation in an isotropic medium is expressed analytically. The

Short-range order (SRO) is introduced into the electronic structure calculation with the KKR-cluster CPA using the probability densities of Markovian pair type. This formalism is applied to Cu 0.5 Pd 0.5 . When the probability of SRO is higher, the d

An expression for the density of states (DOS) is derived in the Korringa-Kohn-Rostoker cluster-coherent-potential approximation (KKR-CCPA) using the augmented space method. This expression is applied to the Cu-Pd and Cu-Ag disordered alloys in the 2-

In this work, the nearest neighbor distance between two deuterium atoms in an f.c.c.palladium lattice was estimated by taking into account the effect of an electronic screening cloud. The lattice was assumed to contain a deuterium atom at the nearest

Thermal diffusivities of sputtered SiC thin films were measured by using ac-calorimetric method. X-ray diffractions showed that the as-sputtered samples were in amorphous state and the thermal diffusivity of the SiC thin film was 0.40 cm 2 /s. After
