Abstract: Provided are a magneto-optical material capable of enhancing the tunable range of magneto-optical properties such as the Faraday rotation angle, and a method for producing the same. The temperature of a substrate 20 is controlled to a first temperature within the range of 300 to 800 [° C.], and the atmospheric pressure of the substrate 20 is controlled to 1.0×10−4 [Pa] or less (first step). Using a composite target or plurality of individual targets of a TCO material exhibiting ENZ properties in the infrared wavelength region, together with a magnetic metal, a magneto-optical material 10 is deposited on the substrate 20 while the temperature of the substrate 20 is controlled to a second temperature within the range of 300 to 800 [° C.], and the atmospheric pressure of the substrate 20 is controlled to the range of 0.1 to 10 [Pa] (second step).

Abstract: Provided is a vibration power generation element that can have improved property of piezoelectricity and mechanical robustness, while having a reduced cost. A piezoelectric layer (20) is formed on a substrate (10), which is supported on a support member (11) in a cantilever state, with a dielectric layer (102) interposed there between. A pair of comb electrodes (41, 42) are formed on the piezoelectric layer (20) that include comb portions (412, 422) extending in a direction (i.e., transverse direction) perpendicular to the extension direction (i.e., longitudinal direction) of the substrate 10 and disposed so as to be fitted into one another.

Abstract: An object of the present invention is to provide a magneto-optical material capable of exhibiting the Faraday effect even though no magnetic field is applied. The magneto-optical material of the present invention has a nanogranular structure in which magnetic nanoparticles are dispersed in a fluoride matrix, and can exhibit Faraday properties without requiring the application of a magnetic field because the magnetic nanoparticles are configured by a magnetic material that has residual magnetization and consists of any of a Fe—Pt alloy, a Co—Pt alloy, a Fe—Co—Ni—Al alloy, a Co ferrite, or a Ba ferrite.

Abstract: Provided is a force sensor capable of expanding the application range of an electrically conductive member having an isotropic gauge factor. The electrically conductive member is placed in a designated latitude region on a main face of the strain body to annularly extend around a pole and to be divided at a position. The designated latitude region is a latitude region in which the magnitude of the sum of a first strain amount in the longitude line direction of the strain body relative to the pole and a second strain amount in the latitude line direction is not less than a reference value when a force having a component in the perpendicular direction to the main face is applied to the strain body.
