Abstract
At −195°C the hysteresis loops of certain yttrium iron garnet cores are strongly affected by a large magnetic field applied as the cores are cooled from room temperature. In order for this magnetic annealing effect to occur, the dc resistivity at room temperature must be less than 109 ohm‐cm. The hysteresis loops, permeability and pulse response of these cores have been measured at −195°. The magnetic behavior of the annealed cores at this temperature can be explained qualitatively by assuming that the domain walls do not move under the influence of magnetic fields less than a critical value.This publication has 1 reference indexed in Scilit:
