Method for increasing the effectiveness of a magnetic field for magnetizing cobalt-rare earth alloy

Method for increasing the effectiveness of a magnetic field for magnetizing cobalt-rare earth alloy

A cobalt-rare earth alloy sintered product is substantially magnetized by heating or cooling it to a temperature at which its intrinsic coercive force Hci is significantly lower than at room temperature, applying a relatively small magnetizing field to it at such temperature and cooling or warming i...

Zusammenfassung:A cobalt-rare earth alloy sintered product is substantially magnetized by heating or cooling it to a temperature at which its intrinsic coercive force Hci is significantly lower than at room temperature, applying a relatively small magnetizing field to it at such temperature and cooling or warming it in the magnetizing field to room temperature.
