A comprehensive framework for hard-magnetic beams: Reduced-order theory, 3D simulations, and experiments

Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Arefeh Abbasi

Thin beams made of magnetorheological elastomers embedded with hard-magnetic particles (hard-MREs) are capable of large deflections under an applied magnetic field. We propose a comprehensive framework, comprising a beam model and 3D finite element modelin ...

Nonreciprocal surface acoustic wave propagation via magneto-rotation coupling

Dirk Grundler, Mingran Xu

A fundamental form of magnon-phonon interaction is an intrinsic property of magnetic materials, the “magnetoelastic coupling.” This form of interaction has been the basis for describing magnetostrictive materials and their applications, where strain induce ...

Magnetic and structural properties of Ni-substituted magnetoelectric Co4Nb2O9

Henrik Moodysson Rønnow, Ivica Zivkovic, Virgile Yves Favre, Hadi Papi, Hossein Ahmadvand

The magnetic and structural properties of polycrystalline Co4-xNixNb2O9 (x = 1, 2) have been investigated by neutron powder diffraction, magnetization and heat capacity measurements, and density functional theory (DFT) calculations. For x = 1, the compound ...

Test Setup for Characterisation of Biased Magnetic Hysteresis Loops in Power Electronic Applications

Drazen Dujic, Min Luo, Jost Allmeling

Hysteresis effect of core materials contributes sig- nificantly to the power loss and nonlinearity of the transformers and filter inductors in power electronic applications. For design or modeling of the magnetic components, information of the magnetic mat ...

Study and Characterization of Magnetic Materials for Beam Intensity Monitors at CERN

Silvia Aguilera Murciano

The number of particles in the beams used at CERN is measured by a family of devices called the Beam Current Transformers (BCTs). One of such devices is the DC Current Transformer (DCCT) measuring the total number of particles in an accelerator. The DCCT i ...

Study and characterization of soft magnetic materials for beam intensity monitors at CERN

Heinrich Hofmann, Silvia Aguilera Murciano

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 ...

Anisotropic magnetic polymer nanocomposite with self-assembled chains of titania-coated magnetite nanoparticles

Yves Leterrier, Tommaso Nardi

An anisotropic magnetic nanocomposite has been prepared by incorporating magnetite nanoparticles (average size: 19nm) in titania (TiO2) particles with a typical size of about 100nm, which are sub- sequently dispersed in a liquid epoxy monomer cured under a ...
