HIGH T_c SUPERCONDUCTIVITY FIRSTS

• FIRST to explain unusual magnetic levitation by ATTRACTION.

• FIRST to prepare thin films by LASER ABLATION of high temperature superconductors.

• FIRST to show existence of both flux CREEP and flux DIFFUSION in high temperature superconductors.

• FIRST to discover sample TEXTURE effects in Mössbauer spectra of high temperature superconductors.

• FIRST to measure the Magnetic properties of UNTWINNED high temperature superconductors.

• FIRST to observe individual ATOMS in a high temperature superconductor below T_c in a FIELD ION MICROSCOPE (Science Magazine Cover: 1/8/88).

• FIRST to IMAGE magnetic flux penetration and trapping in a high temperature superconductor (using the MOIF technique).
