      The objective of this paper is to show that, using magnetic field modulation with a MEMS resonator, it is possible to reduce the noise floor of a commercial Tunneling Magnetic Resistance by one order of magnitude, in the ...

    • Method for forming a magnec field of arbitrary shape from an established template 

      Torrents Dolz, Josep M.; Juan García, Pablo; Sánchez Moragues, Miguel Ángel (Universitat Politècnica de Catalunya (UPC), 2013)
      Text en actes de congrés
      Accés obert
      A strategy to design a particular form of magnetic field along an axis from a coaxial inductor is described. The procedure is illustrated with the design of a constant magnetic field inside a cubic inductor. It validates ...

    • On the ridge of instability in ferrofluidic Couette flow via alternating magnetic field 

      Altmeyer, Sebastian Andreas (2021)
      Text en actes de congrés
      Accés obert
      There is a huge number of natural and industrial flows, which are subjected to time-dependent boundary conditions. The flow of a magnetic fluid under the influence of temporal modulations is such an example. Here, we perform ...
