Magnetic head and magnetic recording and reproducing device

A magnetic head, comprising:

• a magnetic pole;
• a first shield;
• and
• a stacked body provided between the magnetic pole and the first shield,
• the stacked body including
• a magnetic layer including at least one selected from the group consisting of Fe, Co, and Ni,
• a first conductive layer provided between the magnetic pole and the magnetic layer, the first conductive layer being nonmagnetic, and
• a second conductive layer provided between the magnetic layer and the first shield, the second conductive layer being nonmagnetic,
• the first conductive layer including Ir,
• a thickness of the first conductive layer along a first direction being not less than 0.3 nm and not more than 0.8 nm, the first direction being from the first conductive layer toward the second conductive layer,
• the second conductive layer including at least one selected from the group consisting of Cu, Ag, Al, and Au,
• wherein the magnetic pole includes:
• a magnetic pole portion;
• and
• a first intermediate layer provided between the magnetic pole portion and the stacked body, and
• the first intermediate layer includes at least one selected from the group consisting of Fe, Co, and Ni.
