| Abstract: | The anisotropic permanent magnetic composite consisting of HDDR-Nd-Fe-B,ferrite powder and plastic has been prepared,and their magnetic properties have been studied.The experimental results show that magneitc properties b H c and density of anisotropic HDDR-Nd-Fe-B/ferrite permanent magnetic composite almost increase linearly by adding HDDR-NdFeB.However,the magneitc properties j H c,Br, (BH) max, rise with the increasement of HDDR-Nd-Fe-B,when they attain to a value,change a little with the increasement of HDDR-NdFeB,after that,they continue to increase with HDDR-NdFeB increasement.The proportion of ferrite and HDDR-NdFeB powder is different when there is little increasement of j H c, B r and ( BH) max.This is due to that there is different interaction between magnetis powder with different magnetic property along with the change of proportion of ferrite and HDDR-NdFeB.The type of epoxy resin influences obviously on the magnetic property of the anisotropic permanent magnetic composite consi |
