Magnetic circular dichroism of the S 2p, Co 2p, and Co 3p core absorption and orbital angular momentum of the Co 3d state in low-spin CoS2

Magnetic circular dichroism (MCD) has been measured for ferromagnetic CoS2 in the S 2p, Co 2p and 3p core absorption regions. MCD in the S 2p region is discussed in terms of the exchange splitting of the unoccupied band. The Co 2p MCD has revealed that the orbital angular momentum of the Co 3d state remains finite in spite of its low-spin configuration. This situation is confirmed by a simple cluster model calculation

密度成層を考慮した山地流域における風の場の解析

application/pdfA new analytical method of wind field considering stratified atmosphere is presented. The analytical solutions of wind u, v, and w were obtained by using the perturbation method and double Fourier Transform for the basic equations. The solutions can be applied for arbitrary topography of basins in meso-βA scale. The results of analysis show following characteristics. 1) Ascending wind is suppressed by stratification effects of atmosphere comparing with potential flow. 2) In the case of the range of mountain, it is shown that blocking appears in the case of less than the critical internal Froude number. 3) In the case of internal Froude number sufficiently larger than the critical number, the solution approarchs asymptotically the one for potential flow
