The method of sample preparation bulge one layered magnetic thin film material

The present invention discloses a fill material and a preparation method for preparing a magnetic material laminated blister film for a sample, and using an electromagnetic method of preparing a layered film material bulge of the filler sample. Firstly, precision micromachining mining method, a through hole machined on silica substrate. Then mixing a special material filling the vias, and metallographic polished. By the ion plating method and a sputtering electrode on a bottom annular surface of the substrate, and then sol-gel method using the ferroelectric thin film are sequentially deposited and a ferromagnetic film, an annealing treatment, cleaning the surface of the film deposited on the top electrode and dried to a ring. Of analytically pure acetone and then etching solution of sodium hydroxide, removing the through hole filling material, forming a freestanding film window, an electromagnetic film bulge test samples suitable bulge. This method is simple, high production efficiency, a suitable electromagnetic functional film sample preparation method of the blister package material is a drum test.
