A filter for both a differential mode and a common mode is provided. A filter for both a differential mode and a common mode according to an embodiment of the present invention comprises: a pair of series inductors having a plurality of coil patterns; two pairs of parallel capacitors connected to opposite ends of the pair of inductors, respectively; and a pair of series capacitors connected to the pair of inductors in parallel. Therefore, the filter can be used in both a common mode and a differential mode, and can remove noise without using an additional filter in an application having a comparatively high data processing speed.

Filter for both differential mode and common mode

Provided is a magnetoresistance device. The device includes a substrate, a lower layer formed on the substrate, and a magnetoresistance structure formed on the lower layer, and the lower layer is formed of amorphous ZrAl(0&#x3c;x&#x3c;1) or ZrAlO(0&#x3c;x&#x3c;1, 0&#x3c;y&#x3c;1). In a tunneling magnetoresistance (TMR) device, a tunneling barrier layer is formed of at least one selected from the group consisting of ZrAlO(0&#x3c;x&#x3c;1, 0&#x3c;y&#x3c;1), TiAlO(0&#x3c;x&#x3c;1, 0&#x3c;y&#x3c;1), and NbAlO(0&#x3c;x&#x3c;1, 0&#x3c;y&#x3c;1).
