Description

technical field [0001] The invention belongs to the field of magnetic material preparation, and in particular relates to an alkali corrosion-resistant organic magnetic material and a preparation method thereof. Background technique [0002] Magnetic materials, commonly referred to as magnetic materials, refer to strong magnetic substances, which are ancient and widely used functional materials. Modern magnetic materials have been widely used in our lives, such as using permanent magnet materials as motors, core materials used in transformers, magneto-optical disks used as memories, magnetic recording floppy disks for computers, etc. According to Dabit Information, magnetic materials are closely related to informatization, automation, mechatronics, national defense, and all aspects of the national economy. It is generally believed that magnetic materials refer to substances that can directly or indirectly generate magnetism from transition elements such as iron, cobalt, nick...
