We report the electronic properties of R4PtAl (R = Ho, and Er), which contains three sites for R, by measurements magnetization (ac dc), heat-capacity, transport, magnetoresistance (MR). Dc data reveal antiferromagnetic order below 19 K 12 in Ho Er compounds, respectively. Additional features observed at lower temperatures (12 Ho4PtAl 5 Er4PtAl) are akin to cluster spin-glass phase. Resistivity...

To accurately estimate population dynamics and viability, structured population models account for among-individual differences in demographic parameters that are related to individual state. In the widely used matrix models, such differences are incorporated in terms of discrete state categories, whereas integral projection models (IPMs) use continuous state variables to avoid artificial class...

We generalize the concept of fuzzy point, intutionistic fuzzy point, cubic point by introducing the concept of neutrosophic cubic point. Based on neutrosophic cubic point we generalized the idea of ( ; )-fuzzy ideals, ( ; )-intutionistic fuzzy ideals, ( ; )-cubic ideals ideals by initiating the new concept of neutrosophic Cubic ( ; )-ideals. Particularly we give the idea of neutrosophic cubic (...

If the full scientific and technological potential of mesostructured materials is to be achieved, systems with continuous domains in the form of single crystals or films must be prepared. Here we report a reliable and facile system for making large single-crystal particles of chalcogenido mesostructured materials with a highly organized cubic structure, accessible pore structure, and semiconduc...

Local atomic structures of Zr and dopant cations in zirconia solid solutions with Fe,03, Ga203, Y203, and Gd203 .have been determined. The Zr ions in both partially stabilized tetragonal and fully stabilized cubic zirconia have their own characteristic structures which are dopant-independent. The dopant cations substitute for Zr ions despite severe local distortions necessitated by the large di...
