Title: High frequency magnetic material
Inventor: MASUMOTO TAKESHI
IPC: H01F1/147
Filed: 1990-03-09
Abstract: PURPOSE:To obtain high efficient permeability by dispersing BN in a range of 0.54-1.6wt% throughout a Ni-Fe-Mo alloy matrix that is an alloy soft magnetic material. CONSTITUTION:Boron nitride BN is dispersed in a range of 0.54-1.6wt% throughout a Ni-Fe-Mo alloy matrix that is an alloy soft magnetic material. The amount of BN as the dispersion medium over 0.54wt.% causes insufficient action as the dispersion medium; while the amount of BN over 1.6wt.% decreases efficient permeability markedly. Dispersion in a range of 0.54-1.6wt.% makes BN that is an electric insulator disperse throughout a magnetic material; therefore, electric resistivity in the material increases. This keeps the loss of eddy current small even in use over a high frequency range so as to hold high efficient permeability.

Filed: 1988-03-14
Abstract: PURPOSE:To enable the non-linear operation of a GaAs MESFET to be canceled or shift to a higher voltage side by a method wherein the total concentration of boron and carbon contained in a mother material is made equal to or larger than a specified concentration. CONSTITUTION:A GaAs substrate, whose total impurity concentration of boron and carbon is equal to or more than 2X10<17>cm<-3>, is used as a mother material 11, and electrode layers 141 and 142 and an active layer 17 are formed thereon through the implantation of Si ions, which are subjected to a capless annealing in an arsenic atmosphere at a temperature of 850 deg.C for 15 minutes to make the ion implanted layers electrically activated. And, then a gate electrode 18, a source electrode 19, and a drain electrode 20 are formed through a lift-off method. In a MESFET, a leakage current flowing through the part other than the active layer 17 and the electrode layers 141 and 142 usually starts oscillating when a drain voltage is made to increase so as to reach to a certain value or more. But, the fuzzy part under the active layer can be made to disappear by making the total concentration of boron and carbon contained in the mother material 1 equal to or more than 2X10<17>cm<-3> so that a substrate leakage current can be eliminated.
