Metamaterials have been a hot issue in the international research community over the past decade, among which the left-handed material (LHM) is the most typical one that possesses simultaneously negative permittivity and permeability and has unique electromagnetic properties. Although the physical nature of the LHM is equivalent to the continuous medium, in fact LHM is made of artificial metal structure and the physical properties are determined by the parameters of the structure rather than the intrinsic property of the material. Utilizing directly the functional materials'intrinsic physical properties which can generate negative electromagnetic parameters so as to obtain the left-handed properties can greatly enrich the physical characteristics of the LHM and jump out of the scope of design of metamaterial, which is also the characteristic research field in the research field of the LHM. There have been many studies on LHM with ferromagnetic medium in recent years. In this article, we will review the progress of LHM with ferromagnetic medium.
