Magnetic head and magnetic recording device

A magnetic head, comprising:

• a first magnetic pole;
• a second magnetic pole;
• a magnetic element provided between the first magnetic pole and the second magnetic pole, and including a first magnetic layer;
• and
• a magnetic member including a first magnetic part, a second direction from the first magnetic part to the magnetic element crossing a first direction from the first magnetic pole to the second magnetic pole;
• a conductive member including a first conductive part;
• and
• a plurality of terminals,
• the first magnetic part including a magnetic material including at least one of a first material, a second material or a third material,
• the first material including at least one selected from the group consisting of Mn3Sn, Mn3Ge and Mn3Ga,
• the second material including at least one selected from the group consisting of a cubic or tetragonal compound including Mn and Ni, a cubic alloy including γ-phase Mn, and a cubic alloy including Fe,
• the third material including an antiferromagnet, and
• a direction from the first conductive part to the first magnetic part being along the second direction.
