We present experimental evidence for a quantum phase transition in the easy-axis S=3/2 anisotropic quasi-one-dimensional ferromagnet CoCl2⋅2D2O in a transverse field. Elastic neutron scattering shows that the magnetic order parameter vanishes at a transver ...
Magnetic materials hosting correlated electrons play an important role for information technology and signal processing. The currently used ferro-, ferri- and antiferromagnetic materials provide microscopic moments (spins) that are mainly collinear. Recent ...
We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic in-plane angular ...
Electronic nematic materials are characterized by a lowered symmetry of the electronic system compared to the underlying lattice, in analogy to the directional alignment without translational order in nematic liquid crystals1. Such nematic phases appear in ...
At CERN, the circulating beam current measurement is provided by two types of transformers, the DC Current Transformer (DCCT) and the Fast Beam Current Transformer (FBCT). Each transformer is built based on toroidal cores made from a magnetic material. Dep ...
Collective magnetic excitations are a fascinating aspect of condensed matter physics, where neutron scattering can provide valuable insight into the magnetic properties of physical realisations of model systems. This thesis focuses on the excitation spectr ...
Inductive detection with double-balanced coils and a spatial phase profile were used to identify copper and steel rods in a composite target. The electromagnetic detection system was designed and validated using a dipole model. Simulations and experiments ...
This thesis has been put in place during the development of an innovative medical device which consists in an intelligent footwear for foot plantar pressure redistribution in diabetic patients. In fact, despite the several sophisticated techniques develope ...
In this thesis I study the synthesis and basic physical properties characterization on 3d, 4d and 5d transition metal compounds. Great success has been obtained in 3d transition metal compounds, in which the electric states are well localized due t ...
Intensive developments of plasmonic nanomaterials over recent decades have inspired appealing applications in biosensing, optical trapping, fluorescence enhancement and light harvesting in solar cells. These nanostructures supporting unique light-matter in ...
