[0002] Permanent magnetic materials, also known as hard magnetic materials, refer to magnetic materials that can retain their strong magnetism for a very long period of time after being magnetized in some external magnetic fields. They have high coercivity. Permanent magnetic materials are the earliest discovered and applied by humans. At the same time, they are also the magnetic materials with various types, rapid development and wide application. Magnetic materials usually have high coercivity, and their coercivity HC is generally not less than 10A4 / m. Once magnetized and have a high magnetic energy product, they have a high degree of stability in maintaining magnetism when disturbed by external magnetic fields, temperature, vibration, etc.
