Journal ArticleDOI
Small-angle neutron scattering correlation functions of bulk magnetic materials
Denis Mettus,Andreas Michels +1 more
TL;DR: On the basis of the continuum theory of micromagnetics, the correlation function of the spin-misalignment small-angle neutron scattering cross section of bulk ferromagnets is computed and discussed.
Journal ArticleDOI
Microstructural-defect-induced Dzyaloshinskii-Moriya interaction
Andreas Michels,Denis Mettus,Ivan Titov,Artem Malyeyev,Mathias Bersweiler,Philipp Bender,Inma Peral,Rainer Birringer,Yifan Quan,Patrick Hautle,Joachim Kohlbrecher,Dirk Honecker,Jesús Rodríguez Fernández,Luis Fernández Barquín,Konstantin L. Metlov +14 more
TL;DR: In this paper, the authors show that the microstructural-defect-induced DMI gives rise to a polarization-dependent asymmetric term in the small-angle neutron scattering (SANS) cross section of polycrystalline ferromagnets with a centrosymmetric crystal structure.
Journal ArticleDOI
Effect of Dzyaloshinski-Moriya interaction on elastic small-angle neutron scattering
TL;DR: In this article, the impact of the DMI on the magnetic small-angle neutron scattering (SANS) cross section was studied, which is able to probe longwavelength magnetization fluctuations in the bulk and on the nanometer length scale.
Journal ArticleDOI
Spin structures of textured and isotropic Nd-Fe-B-based nanocomposites: evidence for correlated crystallographic and spin textures
Andreas Michels,Raoul Weber,Ivan Titov,Denis Mettus,Elio Alberto Perigo,Inma Peral,Oriol Vallcorba,Joachim Kohlbrecher,Kiyonori Suzuki,Masaaki Ito,Akira Kato,Masao Yano +11 more
TL;DR: In this paper, a comparative study of spin microstructure in Nd-Fe-B nanocomposites, promising materials for permanent-magnet applications, is presented, where a combination of synchrotron x-ray and neutron data shows nanoscale inhomogeneities in the magnetization distribution, and correlation between crystallographic and spin texture.
Journal ArticleDOI
Magnetic microstructure of a textured Nd–Fe–B sintered magnet characterized by small-angle neutron scattering
Elio Alberto Perigo,Denis Mettus,Elliot P. Gilbert,Patrick Hautle,Nemanja Niketic,B. van den Brandt,Joachim Kohlbrecher,P. McGuiness,Zhendong Fu,Andreas Michels +9 more
TL;DR: The results of a small-angle neutron scattering (SANS) study on the magnetic microstructure of a textured Nd-Fe-B-based sintered permanent magnet were reported in this article.
