Abstract

An experimental method has been developed to determine the properties of a thin magnetic film deposited on a wire. The film has a nominal circumferential easy axis; a deviation from this direction is defined as skew, while a local distribution of the direction is defined as dispersion. To give information on skew and dispersion, a method of displaying an envelope of pulsed signals is shown. In magnetic memories, short lengths of the wire are magnetized. The influence of local demagnetizing fields is shown to be important in interpreting the display and assigning value to the anisotropy field. The effects of creep, an increase in length of the magnetized section with repeated pulses, are considered.
