Abstract: A lithium-ion rechargeable battery 1 includes: a stainless-steel substrate 10; a negative electrode layer 20 that contains a negative-electrode active material and is laminated on the substrate 10; a solid electrolyte layer that contains an inorganic solid electrolyte having lithium-ion conductivity and is laminated on the negative electrode layer 20; a positive electrode layer 40 that contains a positive-electrode active material and is laminated on the solid electrolyte layer 30; and a positive electrode collector layer 50 that is composed of titanium and is laminated on the positive electrode layer 40. The boundary portion of the solid electrolyte layer 30 and the positive electrode layer 40 in the lithium-ion rechargeable battery 1 is provided with a mixture layer 70 in which the positive-electrode active material and the inorganic solid electrolyte are mixed. These increase the discharge capacity of the all-solid lithium-ion rechargeable battery.

Abstract: A magnetization measurement device includes: a current supply part supplying a periodically changing current to a sample made of a soft magnetic material with uniaxial magnetic anisotropy in a first direction and a bias magnetic field applied in a second direction crossing the first direction; a light irradiation part irradiating a surface of the sample with linearly polarized pulse light having a predetermined delay time with respect to the current and having a predetermined polarized surface; and a measurement part measuring magnetization of the sample at the delay time based on reflected light of the pulse light reflected by the surface of the sample. These enable the measurement of the change in the magnetization of the sample over time, which corresponds to supply of the periodically changing current.

Abstract: A magnetic sensor 1 includes a plurality of sensitive elements 31 made of a soft magnetic material. The sensitive elements 31 have a longitudinal direction and a transverse direction and have a uniaxial magnetic anisotropy in a direction intersecting the longitudinal direction. The sensitive elements 31 are configured to sense a magnetic field by a magnetic impedance effect. The sensitive elements 31 are arranged with a gap in between in the transverse direction. The magnetic sensor 1 includes a connecting portion 32 configured to connect longitudinal ends of transversely adjacent ones of the sensitive elements 31. The connecting portion 32 has a width in the transverse direction that narrows as the connecting portion 32 approaches the ones of the sensitive elements 31 along the longitudinal direction.
