概要: Measurements of the magnetization and the Hall resistivity have been made on the polycrystals of HoAg_<1-x> In_< ;x> compounds. The compound is antiferromagnetic for x=0~0.2 and ferromagnetic for x=0.3~0.5. The Néel and the Curie temperatures take maximum around x=0.1 and 0.4, respectively. The ordinary Hall coefficient is positive for all the compounds. It takes minimums at z≒0.1 and 0.4 where the magnetic transition temperature takes maximums. The spontaneous Hall coefficient R_s is negative for x=0, 0.1, and 0.5 and positive for x=0.2~0.4. It takes a maximum at x≒0.3. The behavior of R_s is not the same manner as the three compound systems of RAg_<1_x> In_x (R=Gd, Tb, and Dy), and cannot be explained by the localized spin model only. 続きを見る

概要: Rock bodies are assumed to be composed of a two elements Maxwell and a generalized Maxwell model. The finite element formulation of these two viscoelastic materials is that viscous term within constitutive equation of the materials is regarded as initial strain and the unknown displacements are calculated for suitable time interval by the stiffness equation which is derived from the variational principle of elasticity. The resultant computer program of the two elements Maxwell model is adopted to a simple problem of stress response in order to be tested. Numerical and analytical solutions fit well together. It is interesting that tensile stress is observed parallel to contractive strain in this test. 続きを見る
