A Multifrequency-Resonator-Based System for High-Sensitivity High-Field EPR Investigations of Small Single Crystals

In this paper, we describe a multifrequency spectroscopic system which is ideally suited to EPR investigations of very small single crystals. Our method utilizes oversized resonant cavities and a continuously tunable vector network analyzer. This system provides excellent sensitivity over a broad frequency range from about 30 GHz up to about 120 GHz, and in magnetic fields up to 33 T.

Multilayers for high-To superconducting electric field effect devices

Epitaxial multilayers, consisting of a PrBa2Cu307_ x buffer layer, ultrathin YBa2Cu307_ x and SrTiO 3, have been grown for application in electric field effect devices. Different analytical techniques indicate a sharp interface between the layers and good dielectric properties of the SrTiO3-1ayer. First measurements show clear modification of the superconductor's current-voltage characteristics...

Atomic hydrogen as high-precision field standard for high-field EPR.

We introduce atomic hydrogen trapped in an octaisobutylsilsesquioxane nanocage (H@iBuT₈) as a new molecular high-precision magnetic field standard for high-field EPR spectroscopy of organic radicals and other systems with signals around g=2. Its solid-state EPR spectrum consists of two 0.2 mT wide lines separated by about 51 mT and centered at g≈2. The isotropic g factor is 2.00294(3) and essen...

Magnet and Gradient Coil System for Low-Field EPR Imaging

Air-core coils are more practical than iron-core magnets for producing the required magnetic field distribution for electron paramagnetic resonance imaging at frequencies of a few hundred megahertz. An air-core, air-cooled magnet/gradient coil system is presented in this paper, which is optimum in the sense that mathematically it produces fields, which for the number of coils specified, are as ...

Nb3Sn Wire Technology for High-field Superconducting Magnet

Nb3Sn superconducting wires are widely used for highfield superconducting magnets, and the NMR magnet is one of the most successful applications. In order to realize a large Jc (critical current density), which is essential to high-field superconducting magnets, several different types of production methods have been developed, such as the bronze-route method, the powderin-tube method and the i...
