 note = {http://ci.nii.ac.jp/naid/110002288165/ | http://ci.nii.ac.jp/naid/110002288165/, Plastic-bonded magnets were prepared by magnetic field injection molding, using a mixture of Nd_2Fe_<14>B and SrO・6Fe_2O_3 pellets. The magnetic characteristics and temperature coefficients of these magnets were investigated. The hysteresis loop for the temperature change of the plastic-bonded magnet was measured. An important phenomenon was revealed pertaining to the physical properties of the magnetic material : under ordinary temperature conditions, the magnetic temperature coefficient of magnetic flux density and coercive force for the Nd_2Fe_<14>B and SrO・6Fe_2O_3 plastic-bonded magnet for the case of adequate SrO・6Fe_2O_3 content attained a posilive value at a SrO・6Fe_20_3 content ranging from about 20 to 60 mass% at 297-323 K, and from around 18 to 43 mass% at 323-373 K. Moreover, it was proven that the temperature coefficients of the magnetic flux density at operating points of permeance coefficients P_C(B/H)=1 and 2 could be controlled from 0 to 0.22 %/K at 297-323 K and from 0 to 0.1 %/K at 323-373 K, respectively., rights: 社団法人日本セラミックス協会
