Domain wall effects in neutron depolarisation in Co-Cr films

Domain wall effects in neutron depolarisation in Co-Cr films

A long-standing question connected with the magnetisation reversal mechanism in Co-Cr film is whether the film is to be considered as a continuous magnetic medium or as a medium composed of crystallites with parallel c-axes behaving magnetically as a collection of particles. A possibility to shed light on this question is to investigate the thickness of the domain walls (DWs). In a continuous m...

STRIPE DOMAINS IN MAGNETISED Co-Cr FILMS MEASURED BY NEUTRON DEPOLARISATION

A stack of Co-Cr layers sputtered on polyester is magnetised in plane. After reducing the magnetising field to zero, the presence of stripe domains parallel to the former field direction is demonstrated in a transmission experiment with polarised neutrons, using 3D polarisation analysis.

Domain structures and temperature-dependent spin reorientation transitions in c-axis oriented Co–Cr thin films

Highly c-axis oriented Co95Cr5 films with perpendicular anisotropy were grown epitaxially on Si ~111!, using an Ag seed layer, by physical vapor deposition. Films were characterized by x-ray diffraction, transmission electron microscopy ~TEM!, selected area electron diffraction, and Lorentz microscopy in a TEM. The following epitaxial relationship was confirmed: (111)Sii(111)Agi(0001)CoCr ;@ 2̄2...
