    Opis:
    We now demonstrate that such "uniaxial" particles can allow several quantifiable stable (or metastable) orientations of the magnetic moment within the same particle. A new model is presented with quantitative predictions verified by experiments. The results have important implications for rock magnetism, palaeomagnetism, and magnetic materials research. Firstly, the new model quantitatively accounts for several previously unexplained diverse phenomena exhibited by such single-domain (SD) particles. Including the acquisition of gyroremanences, tiled-impressed anisotropy, and transverse components of reminisce in individual particles. These phenomena are theoretically impossible in idealized uniaxial single domain particles, and could now be used to quantify the deviation of real particles from ideal behavior. Secondly, deflections of the natural remanence vector and computations of the ancient field vector and paleointensity are not only controlled by the shape and distribution of the particles, but also by the possible stable orientations of the moments within single-domain particles. The model is also relevant to other single-domain particle morphologies.

    Opis:
    The volume-independence that occurs when Casimir and magnetic energies were equated was employed to solve for optimal spatial separations. For the magnetic moments of a proton and an electron in the presence of a magnetic field strength that produced the energy associated with the neutral hydrogen line, the distances were 1 nm and 24 nm or the width of an ion channel in a plasma cell membrane and the average synaptic width, respectively. The small discrepancies in orbit-spin magnetic moments of the electron with the magnetic moment of the proton emerged as relevant. Calculation of the radius in the bound (circular) system associated with the required magnetic field strength for the ~3.41·10 -27 A·mX 2 discrepancy solved as the Compton wavelength of the electron. Applications of the approach allowed quantitative convergence between universal photon densities within 1 nm widths as well as integration of the energy from acceleration for estimated upper limits of resting photon masses with Planck’s constant. The results suggest that the physical and chemical properties that define biological systems, particularly the brain, reflect astronomical principles.

    Opis:
    The paper presents the research results for the Fe78Co2Si9B11 amorphous alloy, and after the process of annealing resulting only in the relaxation of the material. The structure relaxations occurring in the volume of test samples lead to the changes in their magnetic and mechanic properties. Therefore the studies on the effect of the structure defects on the properties of these type of materials are important. Understanding the processes occurring during the magnetizing of amorphous alloys can be helpful in the design of modern functional materials for special purposes. The main purpose of this elaboration was to determine the effect of the amorphous structure defects in the state after solidification and after heat treatment on the changes in the magnetizing process and in such parameters as the saturation magnetization and the coercivity field.
