In some insulators, corner charges are fractionally quantized, due to the topological invariant called a filling anomaly. The previous theories of fractional have been mostly limited two-dimensional systems. three dimensions, only cases studied. this study, we derive formulas for anomaly and charge in various crystals with all tetrahedral cubic space groups. We discuss that quantized requires crystal shapes be vertex-transitive polyhedra. show formula is universally given by difference...
Recent studies showed that topologically trivial insulators may have fractionally quantized corner charges due to the topological invariant called a filling anomaly. Such crystal shapes in three dimensions are restricted vertex-transitive polyhedra, which classified into spherical and cylindrical families. The previous works derived formulas of fractional charge for family, corresponds tetrahedral cubic space groups (SGs). In this study, we derive all orthorhombic, tetragonal, hexagonal,...
The critical current density and the irreversibility field were measured before after nickel ion irradiation for Bi-2212 single crystals in an optimally doped or overdoped state a magnetic parallel to direction of irradiation. was theoretically calculated by using summation theory flux creep-flow model. From comparison with experimental results condensation energy estimated each specimen. These are compared similar analysis on three-dimensional Y-123.

(Mn0.24Zn0.09Fe0.67)Fe2O4 (MZF) thin films were grown on Si substrates without and with MOSFETs by pulsed laser deposition (PLD). The of MZF was carried out the following two procedures: (1) “1-step deposition,” in which 300-nm-thick film deposited at 800°C, (2) “2-step 10-nm-thick 800°C 27°C followed post–deposition annealing for 1 h under an O2 pressure 1.3 × 10-3 Pa. For both preparation procedures, epitaxial growth (111)-orientation observed. saturation remanent magnetization depends...
