Outline of Final Research Achievements

The coupling constant between the fine particles of the superconducting state of YBCO are estimated from the previous experimental results. We did the numerical simulation in order to estimate the intensity of the superconducting flux loop. We conclude that the intensity of the magnetic field made by the superconducting flux loop can be detectable by using the normal SQUID technique with a small coil.
We will publish a review article “Spin Glasses” from Elsevier. The article is a chapter of the famous series of “Handbook of Magnetic Materials”.
