摘要：
Magnetic nanomaterials can be used in the construction of devices for information processing and memory storage. For this purpose, they have to enjoy two contradictory properties, from one side being able of keeping for long time magnetization frozen, hence information stored, and from the other side allowing for quick change of magnetization required for fast erasing of memory and rewriting new information. Methods of resolving this dilemma are suggested based on triggering resonance, dynamic resonance tuning, and on quadratic Zeeman effect. These methods make it possible to realize effective regulation of spin dynamics in such materials as magnetic nanomolecules and magnetic nanoclusters.
