Proton polarization above 70% by DNP using photo-excited triplet states, a first step towards a broadband neutron spin filter

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 ...

Magnetic order and low-energy excitations in the quasi-one-dimensional antiferromagnet CuSe2O5 with staggered fields

Helmuth Berger

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 ...

Analytical shape derivatives of the MFIE system matrix discretized with RWG functions

Juan Ramon Mosig, Athanasios Polymeridis

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 ...

High-speed CMOS magnetic angle sensor based on miniaturized circular vertical Hall devices

Radivoje Popovic, Mirjana Banjevic

We present a high-speed CMOS integrated magnetic angle sensor consisting of two 8-contact circular vertical Hall devices (CVHD). The biasing and sensing of the Hall voltage is rotated clockwise for the first device, and counter clockwise for the second one ...

Intertwining of Zeeman and Coulomb interactions on excitons in highly symmetric semiconductor quantum dots

Daniel Oberli

We present an experimental study and develop a group theoretical analysis of the Zeeman effect on excitons in pyramidal semiconductor quantum dots possessing the symmetries of the C3v point group. The magnetic field dependence of the emission pattern origi ...
