Abstract: Domain observations using the Kerr effect have been made on 50-percent Ni-Fe grain oriented tapes of 50-μm (2-mil) and 100-μm (4-mil) thickness. The surface domain patterns differ depending ...
Abstract: Use of coated conductor tapes from high-temperature superconductors is a possible way for better energy efficiency in large magnetic systems for particle accelerators or fusion tokamaks.
They then applied an alternating magnetic field to progressively demagnetize each sample. "Like a tape recorder, we are slowly rewinding the sample's magnetic record," Mansbach explains.
