170. Investigation of magnetic proximity effects in SU/FMI/SE heterostructures

Mr Kamaldeep Dalal (Institute Laue Langevin (ILL))

Magnetism, Superconductivity, Topological Systems, Magnetic Thin Films an other electronic phenomena

Talk (25 + 5 min)

Topological states, potentially leading to the formation of Majorana fermions, have been predicted to emerge in heterostructures of an s-wave superconductor (SU) and a semiconductor (SE) with large spin orbit coupling and split band structure [1]. Incorporation of ferromagnetic materials, such as ferromagnetic insulators (FMI), into the het-erostructures constitutes a promising route for...

11. Magnetic order in skyrmion-hosting magnetic multilayers probed by small-angle neutron scattering and polarized neutron reflectometry

Magnetism, Superconductivity, Topological Systems, Magnetic Thin Films an other electronic phenomena

Talk (17 + 3 min)

Magnetic multilayers (MMLs) composed of alternating ferromagnetic / heavy-metal layers are one of the most technologically promising classes of skyrmion-hosting systems due to number of their advantages, such as skyrmion stability at room temperature and their tunability via layer engineering [1]. Through the combination of broken inversion symmetry and spin-orbit-coupling at the asymmetric...

187. Magnetism of pure and Fe-doped multiferroic CoCr2O4 thin films under strain

Talk (17 + 3 min)

Mutliferroic materials are under investigation due to the prospect of controlling the magnetic state with electrical potentials or vice versa. We present an investigation of thin film multifferroic CoCr$_2$O$_4$ (CCO) in pure and Fe-doped form grown with different crystallographic orientation and strain on either MgAl$_2$O$_4$(001) (MAO) or Al$_2$O$_3$(0001) (ALO) substrates. Bulk CCO shows a...

250. Proximity effect in DyCo thin films investiagted by Polarized Neutron Reflectometry

Magnetism, Superconductivity, Topological Systems, Magnetic Thin Films an other electronic phenomena

Talk (25 + 5 min)

Amorphous Rare-Earth - 3d Transition Metal alloys (RE-3d TM) are fascinating magnetic materials due to the easy, straight-forward tunability of their magnetic properties, depending on temperature and the concentration ratio between the RE and 3d TM components. In this presentation, DyCox thin films sandwiched by two thin Ta layers are discussed that show various intriguing phenomena, e.g. a...

17. Resolving the complex spin structure in Fe-based soft magnetic nanocrystalline material by magnetic small-angle neutron scattering

The present work focuses on the unique ability of magnetic small-angle neutron scattering (SANS) to quantitatively analyze the magnetic interactions, namely the exchange-stiffness constant and the strength and spatial structure of the magnetic anisotropy and magnetostatic fields in (Fe_0.7Ni_0.3)₈₆B₁₄ alloy [1]. This particular compound is a promising...
