We classify all warped $dS_5$ backgrounds in $D=11$ supergravity with enhanced supersymmetry. show that preserving $N=16$ supersymmetries consist of either a stack M5 branes transverse space $\mathbb{R}^5$, or generalized M5-brane configuration $\mathbb{R} \times N_4$, where $N_4$ is hyper-Kahler manifold and the $M5$-brane harmonic function determined by potential on $N_4$. Moreover, we find t...
Single crystals of Mn 1.3 2Ni 0.85 Cu 0.83 BO 5 with the ludwigite structure were obtained by solution-melt method during spontaneous crystallization. The concentration copper, manganese and nickel ions was determined transmission microscopy. Manganese are included in compounds divalent trivalent states. study temperature field dependences showed that we have several magnetic transitions. first...
