    Abstract: This invention prevents measurement error from becoming large in thermoelectric conversion coefficient evaluation and enhances evaluation efficiency. This invention is a physical property evaluation device for evaluating the physical properties of a plurality of solid materials formed on a substrate. The physical property evaluation device comprises an electromotive force measurement means that forms closed circuits including the individual solid materials and measures the electromotive forces occurring at the two ends of each of the solid materials, a means for producing heat flow within the individual solid materials, an external magnetic field generation means for generating a uniform magnetic field having a given intensity and direction in the vicinity of the individual solid materials, and an automation means for evaluating the physical properties of the individual solid materials using the electromotive force measurement means, heat flow production means, and external magnetic field generation means.

    Abstract: A relation search system includes: a storage means (1) which stores a data set which includes a first-type data group and a second-type data group which are two types of data group that are acquired by different methods; a data adaptation means (2) which either corrects or reconstructs either first data which belongs to the first-type data group or second data which belongs to the second-type data group and which is associated with the first data, such that a divergence which arises between the first data and the second data because of the difference in the methods for the acquisition thereof is reduced; and a learning means (3) which, using the data set which includes the corrected or reconstructed data, carries out machine learning.

    Abstract: A heat-flow sensor that includes an insulating layer, a magnetic field application layer arranged on a first surface of the insulating layer and composed of a conductor, and a heat-flow detection layer arranged on a second surface of the insulating layer, the second surface facing the first surface, and the heat-flow detection layer composed of a conductive magnetic body. The heat-flow detection layer faces the magnetic field application layer via the insulating layer.

    Abstract: A thermoelectric conversion element 10 includes an anomalous Nernst material 11 having the anomalous Nernst effect, in which: the anomalous Nernst material 11 includes at least an element having the inverse spin-Hall effect; and the element is spin-polarized. By applying, for example, a magnetic field to such the thermoelectric conversion element 10 in the x direction and a temperature gradient thereto in the z direction, thermoelectromotive force can be taken out from terminals 12.
