Magnetic particle coated material containing magnetic particles having CuAu type or Cu3Au type ferromagnetic ordered alloy phase, and method for producing the same

Abstract

The present invention is a magnetic particle coated material comprising: a first support having a magnetic layer formed on one surface thereof; and a second support having a magnetic layer formed on one surface thereof, wherein the first support and the second support are attached to each other so that the other surfaces thereof on which the magnetic layers are not formed face each other, and the magnetic layers comprise magnetic particles having a CuAu type or Cu 3 Au type ferromagnetic ordered alloy phase.

         13 . A method for producing a magnetic particle coated material, the method comprising: 
 applying an alloy particle-containing solution onto each of two supports;    annealing the supports to form a magnetic layer on one surface of each of the supports, the magnetic layer containing magnetic particles having a CuAu type or Cu 3 Au type ferromagnetic ordered alloy phase; and    attaching the supports to each other so that the other surfaces having no magnetic layers formed thereon face each other,    wherein the supports have substantially the same annealing conditions.    
     
     
         14 . The method of  claim 13 , wherein the supports are simultaneously annealed in the same apparatus.  
     
     
         15 . The method of  claim 13 , wherein the alloy particles in the alloy particle-containing solution are oxidized before the application.  
     
     
         16 . The method of  claim 14 , wherein the alloy particles in the alloy particle-containing solution are oxidized before the application.  
     
     
         17 . The method of  claim 13 , wherein the first support and the second support are attached to each other via an intermediate support.  
     
     
         18 . The method of  claim 14 , wherein the first support and the second support are attached to each other via an intermediate support.  
     
     
         19 . The method of  claim 15 , wherein the first support and the second support are attached to each other via an intermediate support.  
     
     
         20 . The method of  claim 16 , wherein the first support and the second support are attached to each other via an intermediate support.
