Muon-spin-relaxation experiments and ac low-field magnetization measurements have been carried out on the superconductor CeRu2. The relaxation rate of the muon-spin polarization in zero field exhibits a small but significant increase below TM.40 K, which is suppressed by applying a longitudinal field. This result taken together with magnetization measurements provides definite evidence for the ...

Optical linear polarization measurements of association members and field stars in the region of the Puppis OB III association are presented. The association members are found to have larger values of polarization than the field stars.In the direction of the association there are two regions of polarizing interstellar medium with magnetic fields that are nearly at right angles to each other. Th...

This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...

For permalloy/CoO multilayers, the exchange field and the coercivity of the perpendicular and longitudinal exchange biasing have been found to decrease with increasing temperature. After zero field cooling, perpendicular magnetic anisotropy is observed. For small permalloy layer thickness, perpendicular anisotropy film can be established at low temperatures. r 2004 Elsevier B.V. All rights rese...

The effect of uniaxial crystal-field anisotropy on magnetic properties of the superexchange antiferromagnetic Ising model The generalized Fisher super-exchange antiferromagnetic model with uniaxial crystal-field anisotropy is exactly investigated using an extended mapping technique. An exact relation between partition function of the studied system and that one of the standard zero-field spin-1...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

virial theorem is important for understanding stellar structures. it produces an interesting connection between magnetic and gravitational energies. using the general form of the virial theorem including the magnetic field (toroidal magnetic field), we may explain the solar dynamo model in relation to variations of the magnetic and gravitational energies. we emphasize the role of the gravitatio...

Magnetic field  improved germination parameters. The germination of Catharanthus roseus seeds is lost under salinity conditions. The effect of different strengths of magnetic field and exposure durations on the germination of C. roseus seeds under salinity conditions (19 mS cm-1) were investigated. The experiment was conducted  with factorial arrangement based on a completely randomized design ...

The boundary problem in cylindrical coordinates for the Schrödinger equation describing a hydrogen-like atom in a strong homogeneous magnetic field is reduced to the problem for a set of the longitudinal equations in the framework of the Kantorovich method. The effective potentials of these equations are given by integrals over transversal variable of a product of transverse basis functions dep...
