摘要: The present invention offers a minute-sized magnet with superior magnetic energy product (BH)max and coercivity iHc, as well as superior anti-corrosive properties. This magnet is comprised of an alloy comprised of 35-55 atomic % platinum, 0.001-10 atomic % third element, which is one or more elements from groups IVa, Va, IIIb, or IVb, and a remainder of iron and other unavoidable impurities. The average crystal size of this FePt alloy is 0.3 &mgr;m. By mixing an FePt alloy with a specific element in a designated ratio, an FePt magnet with more excellent characteristics than ones made from previous alloys was successfully made.

摘要: An accelerometer for measuring the displacement of a magnet body using magnetic detecting elements is provided, the accelerometer having superior measurement accuracy by suppressing influence of a peripheral magnetic field. The accelerometer has detecting units each having a cantilever which is elastically deformed so as to rotate around a fixed end thereof, a magnet body provided at a free end of the cantilever, and a magnetic detecting head portion disposed outside the rotation region of the cantilever. In order to correct detection signals output from the magnetic detecting head portions, the accelerometer has peripheral magnetic field detecting portions for measuring a peripheral magnetic field acting on the magnetic detecting head portions and the magnet bodies.
