Magnetic susceptibility control of superconducting materials in nuclear magnetic resonance (NMR) probes |
摘要 |
A method and apparatus which utilizes the hysteritic behavior of type II superconductors for reducing the effective magnetic susceptibility of high temperature superconducting materials used close to the sample region in nuclear magnetic system probes. The method is particularly applicable to receiver coils. Reducing the magnetic susceptibility of superconducting receiver coils enables the improved sensitivity they inherently provide to be realized without loss of resolution resulting from line broadening caused by susceptibility discontinuities of materials near the sample region of the probe.
