1. A physical property evaluation device that evaluates a physical property of a solid material having a first end and a second end being formed on a substrate, the device comprising:
an electromotive force measurement unit that forms a closed circuit including the solid material, and measures an electromotive force being generated between the first end and the second end of the solid material;
a heat flow generation unit that generates a heat flow in the solid material;
an external magnetic field generation unit that generates a uniform magnetic field in a vicinity of the solid material, the magnetic field having a given intensity and direction; and
an automation unit that evaluates the physical property of the solid material by using the electromotive force measurement unit, the heat flow generation unit, and the external magnetic field generation unit.
