Popis: We investigated the effects of configuration of thin-film magnetoimpedance element on impedance profile. The parallel type and meander type sensor element were fabricated. The parallel line configuration has advantages to reduce a bias field and to enhance total inductance attributable to positive mutual inductance, while a large number of lines brings a decrement of impedance changes. The meander type induces a large demagnetizing effect and decrement of the total inductance due to negative mutual inductance. However, this configuration can utilize the space of the element, which contributes to enhance spatial resolution.
