    Early stages of mechanical crystallization of amorphous Fe86Zr7B6Cu1 soft magnetic material: The role of shear bands

    No full text
    Nanocrystalline soft magnetic materials can have superior properties such as low coercivity combined with a high saturation magnetization. Whereas these materials are usually made by thermal crystallization of amorphous precursors, mechanical crystallization using ball milling provides an alternative route for the generation of nanocrystalline materials. The focus of this study is the development of the magnetic properties and the microstructure at the early stages of the transformation of initially amorphous Fe86Zr7B6Cu1. Controlled deformation of amorphous starting material by cold rolling is performed to clarify the origin of the coercivity maximum. Optical and magneto-optical investigations reveal the influence of the microstructure on the coercivity. The shear band density obtained from the magneto-optical observations is directly correlated with the increase in coercivity

    Strichartz estimates and global well-posedness of the cubic NLS on T2\mathbb{T}^{2}

    No full text
    The optimal L4L^4-Strichartz estimate for the Schr{ö}dinger equation on the two-dimensional rational torus T2\mathbb{T}^2 is proved, which improves an estimate of Bourgain. A new method based on incidence geometry is used. The approach yields a stronger L4L^4 bound on a logarithmic time scale, which implies global existence of solutions to the cubic (mass-critical) nonlinear Schrödinger equation in Hs(T2)H^s(\mathbb{T}^2) for any s>0s>0 and data which is small in the critical norm.v2: 19 pages, 5 figures. An error (Lemma 3.1 of version 1) has been corrected. v3: minor corrections, additional remarks and references and improved exposition in Section

    Bejenaru I, Herr S. The Cubic Dirac Equation: Small Initial Data in H1/2(R2)H^{1/2}(R^2). Communications in Mathematical Physics. 2016;343(2):515-562.Global well-posedness and scattering for the cubic Dirac equation with small initial data in the critical space H-1/2 (R-2) is established. The proof is based on a sharp endpoint Strichartz estimate for the Klein-Gordon equation in dimension n = 2, which is captured by constructing an adapted systems of coordinate frames
