Dipolar Halbach magnet stacks made from identically shaped permanent magnets for magnetic resonance
NMR Mandhalas (Magnetic Arrangement for Novel Discrete Halbach LAy- out) are arrays of identically shaped magnets in a Halbach-type arrangement. They pro- vide a simple and cost-effective way toExpand

Infrared receptors in pyrophilous (“fire loving”) insects as model for new un-cooled infrared sensors
Summary Beetles of the genus Melanophila and certain flat bugs of the genus Aradus actually approach forest fires. For the detection of fires and of hot surfaces the pyrophilous species of bothExpand

Electromagnetic Simulation and Design of a Novel Waveguide RF Wien Filter for Electric Dipole Moment Measurements of Protons and Deuterons
Abstract The conventional Wien filter is a device with orthogonal static magnetic and electric fields, often used for velocity separation of charged particles. Here we describe the electromagneticExpand

Low‐resistivity epitaxial YBa2Cu3O7 thin films with improved microstructure and reduced microwave losses
Epitaxial thin films of YBa2Cu3O7 have been prepared on SrTiO3 and LaAlO3 substrates by a high‐pressure planar dc‐sputtering technique. By covering the substrate heater with a frame ofExpand

Surface conductivity of Si(100) and Ge(100) surfaces determined from four-point transport measurements using an analytical N-layer conductance model
An analytical N-layer model for charge transport close to a surface is derived from the solution of Poisson's equation and used to describe distance-dependent electrical four-point measurements onExpand

Epitaxial multilayers of YBa2Cu3O7 and PrBa2Cu3O7 as a possible basis for superconducting electronic devices
Abstract The structural and superconducting properties of YBa2Cu3O7/PrBa2Cu3O7 heterostructures on SrTiO3 were studied. It was found that the epitaxy is maintained throughout the layer system.Expand

HTS rf SQUIDs with fully integrated planar tank circuits
For the optimization of the operation of rf-SQUIDs, a high pumping frequency f/sub 0/ and a high quality factor Q of the tank circuit are desirable. For this purpose we used a washer rf SQUID or aExpand

Surface and Step Conductivities on Si(111) Surfaces.
Four-point measurements using a multitip scanning tunneling microscope are carried out in order to determine surface and step conductivities on Si(111) surfaces. In a first step, distance-dependentExpand
