It is well known that a relatively high magnetic anisotropy and magnetic field can induce strain in the polycrystalline Ni-M-Ga alloy, especially, in the preferred <001> orientation. A significant technological improvement may be achieved by producing textured rods with axial orientation. This was realized by rods extrusion at high temperature with a proper reduction rate. The paper concerns the comparison of texture, magnetization and magneto-crystalline anisotropy constant for samples cut out from the columnar grain zone and cut from extruded rods.
