Abstract :
Recently, the magnetoelectric (ME) effect observed in some of spiral magnets has been extensively studied. Especially, Z-type hexagonal Ba3-xSrxCo2Fe12O22 show ME effect via a complex helical spin structures such as heliconical magnet and transverse conical magnet. Also, Z-type hexa-ferrite has been considered for microwave application due to high cut-off frequency and high permeability at GHz. Their properties are strongly affected by the hyperfine distribution in hexagonal structure.
