In the first part of this thesis we describe the functioning principle of the scanning hall probe microscope (SHPM), and we present a summary of the theoretical and experimental knowledge on the dipolar-coupled Ising ferromagnet LiHoF4. In the second chapt ...
In this work, we extend a separate magnitude and phase regularization framework for Phase Contrast MRI by incorporating the divergence-free condition. ...
The use of polarized protons as neutron spin filter is an attractive alternative to the well established neutron polarization techniques, as the large, spin-clepenclent neutron scattering cross-section for protons is useful up to the sub-MeV region. Employ ...

An analytical formula for the shape derivative of the magnetic field integral equation (MFIE) method of moments (MoM) system matrix (or impedance matrix) is derived and validated against finite difference formulas. The motivation for computing the shape de ...

The IceCube Neutrino Observatory is a large Cherenkov detector instrumenting of Antarctic ice. The detector can be used to search for signatures of particle physics beyond the Standard Model. Here, we describe the search for non-relativistic, magnetic mono ...
In an article (Zurcher, Microwave Opt Technol Lett 55 (2013), 516-521) published in 2013, a new antenna called tripod omnidirectional low profile Antenna has been presented. It is vertically polarized and has a radiation pattern similar to the classical mo ...
Using an optimally coupled nanometer-scale SQUID, we measure the magnetic flux originating from an individual ferromagnetic Ni nanotube attached to a Si cantilever. At the same time, we detect the nanotube's volume magnetization using torque magnetometry. ...
Frustrated systems exhibit remarkable properties due to the high degeneracy of their ground states. Stabilised by competing interactions, a rich diversity of typically nanometre-sized phase structures appear in polymer and colloidal systems, while the surf ...
Ground-state and low-energy excitations of the quasi-one-dimensional antiferromagnet CuSe2O5 where finite interchain interactions promote long-range antiferromagnetic order below T-N = 17 K, were experimentally studied using bulk magnetization, neutron dif ...
