Development of novel lightweight and cost-effective Mg–Ce–Al wrought alloy with high strength
Materials Research Letters, 2021 The low microalloying content and high yield strength of 365 MPa have been achieved simultaneously in extruded Mg–Ce–Al alloy which is mainly ascribed to the unexpected grain refinement (mean size of ∼420 nm).

Random-anisotropy-axis magnet with infinite anisotropy
Physical Review B, 1987 We have studied the random-axis magnet with infinite anisotropy by three methods: Cayley-tree approximation, Migdal-Kadanoff renormalization group (MKRG), and Imry-Ma scaling. In the Cayley-tree approximation, by an examination of susceptibilities, it is shown that there exists a competition between the coordination number z and the number of ...

Thermal Oxidation Preparation of Doped Hematite Thin Films for Photoelectrochemical Water Splitting
International Journal of Photoenergy, 2014 Sn- or Ge-doped hematite thin films were fabricated by annealing alloyed films for the purpose of photoelectrochemical (PEC) water splitting. The alloyed films were deposited on FTO glass by magnetron sputtering and their compositions were controlled by ...

Kinematic deprojection and mass inversion of spherical systems of known velocity anisotropy [PDF]
, 2009 Traditionally, the mass / velocity anisotropy degeneracy (MAD) inherent in the spherical, stationary, non-streaming Jeans equation has been handled by assuming a mass profile and fitting models to the observed kinematical data.

Grain refinement and strength enhancement in Mg wrought alloys: A review
Journal of Magnesium and Alloys, 2023 Low absolute strength becomes one major obstacle for the wider applications of low/no rare-earth (RE) containing Mg alloys. This review firstly demonstrates the importance of grain refinement in improving strength of Mg alloys by comprehensively ...

Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films [PDF]
, 2014 In this work we studied a two dimensional ferromagnetic system using Monte Carlo simulations. Our model includes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-plane ones.
