Abstract: A magnetoresistive effect device includes a first magnetoresistive effect element, a second magnetoresistive effect element, a first port, a second port, a signal line, and a direct-current input terminal. The first port, the first magnetoresistive effect element, and the second port are connected in series to each other in this order via the signal line. The second magnetoresistive effect element is connected to the signal line in parallel with the second port. The first magnetoresistive effect element and the second magnetoresistive effect element are formed so that the relationship between the direction of direct current that is input from the direct-current input terminal and that flows through the first magnetoresistive effect element and the order of arrangement of a magnetization fixed layer, a spacer layer, and a magnetization free layer in the first magnetoresistive effect element is opposite to the above relationship in the second magnetoresistive effect element.

Abstract: A magnetoresistive effect device includes a magnetoresistive effect element including a magnetization fixed layer, a spacer layer, and a magnetization free layer; a first port; a second port; a signal line; an impedance element; and a direct-current input terminal. The first port, the magnetoresistive effect element, and the second port are connected in series in this order via the signal line. The impedance element is connected to ground and to the signal line between the magnetoresistive effect element and the first port or the second port. The direct-current input terminal is connected to the signal line at the opposite side to the impedance element with the magnetoresistive effect element in between the direct-current input terminal and the impedance element. A closed circuit including the magnetoresistive effect element, the signal line, the impedance element, the ground, and the direct-current input terminal is to be formed.
