This article is devoted to the application of the method for optimal design of the shell-type electromagnets based on the solving inverse problems of stationary magnetic field theory by finite element method and on the transformation of constraints on magnetic induction and a tractive force in the objective functions. Minimization of these objective functions is performed by gradient descent numerically...
Compounds with the general formula Mg1−x AlxB2 were obtained by two-step ceramic synthesis. All compounds were characterized by X-ray diffraction, NMR spectroscopy, and by four point probe resistivity measurements in various magnetic fields method. The diborides unit cell parameters were determined as a function of the Al mole fraction. With the vaues of x up to 0.40 (where...
