Magnetic field dependence of the basal-plane superconducting anisotropy in YBa2Cu4O8 from small-angle neutron scattering measurements of the vortex lattice

We report a study of the basal-plane anisotropy of the superfluid density in underdoped YBa2Cu4O8 (Y124), showing the effects of both the CuO2 planes and the fully occupied CuO chains. From small-angle neutron scattering measurements of the vortex lattice, ...

Development and Characterization of An Unshielded PatLoc Gradient Coil for Human Head Imaging

Daniel Gallichan, Zhenyu Liu

A cylindrical head gradient insert for human imaging with non-linear spatial encoding magnetic fields (SEMs) has been designed, optimized and successfully integrated with a modified 3T clinical MR system. This PatLoc (parallel acquisition technique using l ...

Modeling of High-Frequency Electromagnetic Effects on an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor (I2PS) is a five-coil air-cored structure that senses the variation of flux linkage between supply and sense coils and relates it to the linear position of a moving coil. In air-cored structures, the skin and proximit ...

Physics in magnetic fields from Michael Faraday to Pierre Weiss & his contemporaries

Jean-François Loude

The mechanical action on iron of the first horseshoe electro-magnets (1824) was obvious. They quickly found important applications (telegraphy). Their use to investigate more subtle magnetic, magneto-optical, atomic or nuclear properties of matter began in ...

Asymmetric Ring/Disk Nanocavities on Conducting Substrates for Strong Fano-Interference

Hatice Altug, Arif Engin Cetin

We introduce a Fano resonant asymmetric ring/disk cavity system employing a conducting layer underneath. Our system shows stronger electromagnetic fields that are highly accessible to surrounding medium and sharper spectral features that result in more rel ...

Evidence for a Magnetic Seebeck Effect

Jean-Philippe Ansermet, Sylvain Bréchet, Francesco Antonio Vetrò, Elisa Papa

The irreversible thermodynamics of a continuous medium with magnetic dipoles predicts that a temperature gradient in the presence of magnetization waves induces a magnetic induction field, which is the magnetic analog of the Seebeck effect. This thermal gr ...

A transmission line model for plasmon propagation on a graphene strip

Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

We present a transmission line model for TM plasmon propagation along a graphene strip, and derive closed-form expressions for the kinetic and Faraday inductance, resistance, and electrostatic capacitance of the equivalent circuit as a function of graphene ...

Integrated analysis of quench propagation in a system of magnetically coupled superconducting coils

Luca Bottura

We demonstrate in this paper how to use direct modeling of heat transfer and circuital equations based on "packaged" simulation tools to produce a model suitable for the study of quench propagation in a system of magnetically coupled solenoids protected wi ...

Flux Observer-Based vector control for Induction Motor

Sébastien Allemand

The induction motor offers the best value for money and is therefore used in many different application fields where power requirements are higher than a few kilowatts. ln order to be able to reduce the priee and the motor's size, a control algorithm based ...
