Observation of a Goos-Hänchen-like Phase Shift for Magnetostatic Spin Waves

Autor: Martin Decker, J. Stigloher, H. S. Körner, Takahiro Moriyama, Christian H. Back, Teruo Ono, Takuya Taniguchi

Publikováno v: Physical Review Letters. 121

In optics, a light beam experiences a spatial shift in the beam plane upon total internal reflection. This shift is usually referred to as the Goos-Hänchen shift. When dealing with plane waves, it manifests itself as a phase shift between an incomin

Excitation and tailoring of diffractive spin-wave beams in NiFe using nonuniform microwave antennas

Autor: J. Stigloher, H. S. Körner, Christian H. Back

We experimentally demonstrate by time-resolved scanning magneto-optical Kerr microscopy the possibility to locally excite multiple spin-wave beams in the dipolar-dominated regime in metallic NiFe films. For this purpose we employ differently shaped n

Combined frequency and time domain measurements on injection-locked, constriction-based spin Hall nano-oscillators

Autor: J. Stigloher, Olav Hellwig, Sri Sai Phani Kanth Arekapudi, T. Weinhold, Jürgen Fassbender, Helmut Schultheiss, T. Hache, Christian H. Back, F. Vilsmeier, Katrin Schultheiss

Publikováno v: Applied Physics Letters 114(2019)10, 102403

We demonstrate a combined frequency and time domain investigation of injection-locked, constriction-based spin Hall nano-oscillators by Brillouin light scattering (BLS) and time-resolved magneto-optical Kerr effect (TR-MOKE). This was achieved by app

We report the experimental observation of Snell's law for magneto-static spin waves in thin ferromagnetic Permalloy films by imaging incident, refracted and reflected waves. We use a thickness step as the interface between two media with different di

Interfacial Dzyaloshinskii-Moriya interaction studied by time-resolved scanning Kerr microscopy

Autor: Christian H. Back, J. Stigloher, Takahiro Moriyama, Takuya Taniguchi, H. S. Körner, H. G. Bauer, Teruo Ono, Hiroshi Hata

Publikováno v: Physical Review B. 92

We investigate the influence of the interfacial Dzyaloshinskii-Moriya interaction (DMI) on the propagation of Damon-Eshbach spin waves in micrometer-sized Pt(2 nm)/Co(0.4 nm)/Py(5 nm)/MgO(5 nm) stripes. We use time-resolved scanning Kerr microscopy t

Spatial constraints on the source of uniaxial anisotropy in (Ga,Mn)As films

Autor: Jean-Yves Chauleau, J. Stigloher, F. Hoffmann, M. Kiessling, Christian H. Back, Georg Woltersdorf, H. S. Körner, V. Novak

Publikováno v: Journal of Physics D: Applied Physics. 47:195001

We use time-resolved Kerr microscopy to perform ferromagnetic resonance experiments on nanostructured elements to show that strain is not the origin of the strong uniaxial in-plane anisotropy observed in (Ga,Mn)As films. From local angular dependent
