発明の名称 (英語) DIAMOND CRYSTAL, DIAMOND ELEMENT, MAGNETIC SENSOR, MAGNETIC MEASUREMENT DEVICE, AND METHOD FOR MANUFACTURING SENSOR ARRAY
発明の概要(英語) Provided is a technique for making two-dimensional magnetic measurement with high sensitivity possible at normal temperature in the atmosphere. The diamond crystal pertaining to the present invention is characterized by having an NV region including a complex (NV center) of nitrogen substituted for a carbon atom and a vacancy adjacent to the nitrogen on or near the surface thereof, the NV region having a donor concentration equal to or greater than the concentration of the NV center, or the crystal in the NV region being the (111) face or a face having an off angle no more than ±10° of the (111) face, and the principal axis of the NV center being a <111> axis orthogonal to the (111) face. Through such a diamond crystal, substantially 100% of the NV center can be placed in a negatively charged state (NV-), the spin state of the NV- center can be aligned in one direction, and ODMR signal peaks also become sharp. Through the sensor array pertaining to the present invention, the NV center generated in the diamond crystal can be maintained in the negatively charged state (NV-).
