Giant Magnetoimpedance: 30 Years Since Rediscovery and Next Steps

In this review, devoted to the 30th anniversary since discovery the giant magnetoimpedance (MI) we analyzed and generalized results of experimental, theoretical studies and perspective of practical applications in this research area. As the MI field in the course of 30 years of intensive studies had created huge number of referenced sources, we made special effort to provide representative bibliography, which can be useful for the future reading. The high sensitivity of MI with respect to applied magnetic field allows us to anticipate that more types of MI and MI biosensors may be developed up to commercial level shortly. However, there are still fundamental and technical problems to understand and solve.
