The many peculiarities of Ap stars (not only chemical ones, but also magnetic field and slow rotation) may vary during the main-sequence evolution of these stars. We review here briefly the evidences found in the last thirty years for such evolution, with ...
The synergy between magnetic field (MF) and electrostatic interactions on the kinetics of radical homopolymerization of acrylamide (AM), acrylic acid (AA), its ionized form acrylate (A ...
Motivated by the remarkable properties of SrCu2(BO3)(2) in a magnetic field, we use perturbative continuous unitary transformations to determine the magnetization plateaux of the Shastry-Sutherland model, unveiling an unexpected sequence of plateaux progre ...
This paper presents a new technique for continuously calibrating the sensitivity of a current measurement microsystem based on a Hall magnetic field sensor. An integrated reference coil generates a magnetic field for calibration. Using a variant of the cho ...
We present a CMOS-based hybrid microfluidic system that combines the manipulation of magnetic microparticles through a magnetic field with in situ optical detection via single photon avalanche diodes (SPADs). Magnetic particles are actuated within a glass ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for contactless 360 degrees absolute angle encoding. The sensing device consists of a narrow n-well ring with a chain of 64 contacts equally distributed along the ring. It is ...

This paper presents a new technique to sense the direction of the magnetic field, enabling a new generation of contactless 360 degrees absolute angle encoders. The sensor consists of a microchip that contains a special ring-shaped Hall element. It is the f ...

Microfabricated probes for Nuclear Magnetic Resonance (NMR) spectroscopy of living cells in very small quantities have been developed in this thesis. These microprobes are based on two different sample interfaces: Channel microprobes, which confine a stack ...
We show that Dzyaloshinskii-Moriya (DM) interactions can substantially modify the phase diagram of spin-1/2 Heisenberg ladders in a magnetic field provided they compete with exchange. For nonfrustrated ladders, they induce a local magnetization along the D ...
