Method and apparatus with magnetic body measurement

An apparatus, comprising:

• a magnetic field generator configured to generate a magnetic space by applying a uniform magnetic field;
• a rotating driver configured to rotate the magnetic body about a predetermined axis in the magnetic space;
• a data measurement device configured to measure a first resistance value and a second resistance value;
• and
• a calculator configured to determine the magnetic anisotropy constant of the magnetic body based on the first resistance value and the second resistance value,
• wherein the first resistance value is a measured resistance value of the magnetic body according to a magnetic field sweep in a direction of a magnetization hard axis of the magnetic body, and
• wherein the second resistance value is another measured resistance value of the magnetic body according to an angle of an external magnetic field, the angle of the external magnetic field being an angle formed by a magnetization easy axis of the magnetic body and a direction of a magnetic field applied to the magnetic body.

An electronic device comprising:

• one or more processors configured to execute instructions;
• and
• one or more memories storing the instructions,
• wherein the execution of the instructions by the one or more processors configures the one or more processors to:
• generate a first resistance value of a magnetic body according to a magnetic field sweep in a direction of a magnetization hard axis of the magnetic body;
• generate a second resistance value of the magnetic body according to an angle of an external magnetic field, the angle of the external magnetic field being an angle formed by a magnetization easy axis of the magnetic body and a direction of a magnetic field applied to the magnetic body;
• and
• determine a magnetic anisotropy constant of the magnetic body based on the first resistance value and the second resistance value.
