Tuning the Magnetic Ordering Temperature of Hexagonal Ferrites by Structural Distortion Control [PDF]

, 2018
To tune the magnetic properties of hexagonal ferrites, a family of magnetoelectric multiferroic materials, by atomic-scale structural engineering, we studied the effect of structural distortion on the magnetic ordering temperature (TN).

Structure of hexagonal ζ´-AlMnCo

Journal of Physics: Conference Series, 2023
Abstract The structure of ζ´-Al80Mn16Co4 was analyzed using single-crystal X-ray diffraction. The diffraction pattern indicated that the ζ´-AlMnCo phase has a hexagonal unit cell with a space group P63/m, a = 30.5173(5) Å, c = 12.4742(2) Å, and the a-axis is

Grid Cell Hexagonal Patterns Formed by Fast Self-Organized Learning within Entorhinal Cortex [PDF]

, 2009
Grid cells in the dorsal segment of the medial entorhinal cortex (dMEC) show remarkable hexagonal activity patterns, at multiple spatial scales, during spatial navigation. How these hexagonal patterns arise has excited intense interest. It has previously

The study of crystal and magnetic properties of MnNi0.85Fe0.15Ge

Nukleonika, 2015
Magnetic and Mössbauer measurements were performed for MnNi0.85Fe0.15Ge. The Mössbauer data indicate that Fe atoms in MnNi0.85Fe0.15Ge are randomly distributed over two types of metal sites in hexagonal structure.

Reentrant hexagonal Turing structures

Physics Letters A, 1992
Abstract A new structural transition from stripes to hexagons is reported for the two-dimensional Brusselator model. Its existence is explained by the properties of the quadratic nonlinear coupling.

An Occupancy Information Grid Model for Path Planning of Intelligent Robots

ISPRS International Journal of Geo-Information, 2022
Commonly used robot map models include occupancy grid maps, topological maps, and semantic maps. Among these, an occupancy grid map is mainly represented as a quadrilateral grid. This paper proposes an occupancy information grid for intelligent robots by
