Film Synthesized Rare Earth Transition Metal Permanent Magnet Systems
Abstract
Specific results of this research include five unique results. (1) The elucidation of the concept of a growth coherence region as being pivotal for the growth of textured polycrystalline films. This concept allows the prediction of what texture modes would be possible for any new system that may be discovered. (2) For the very first time it was demonstrated that pulsed laser deposition can be used to grow highly textured high coercivity rare earth transition metal films with magnetic properties comparable to the best sputtered films. (3) It was shown that the simultaneous use of sputtering and pulsed laser deposition methods can be used to grow nanophase dispersed films with special magnetic and other properties. (4) A new type of magnetoresistive magnetic memory element operable at room temperature was demonstrated for specially deposited La-manganite films when used in conjunction with another magnetic film element. (5) A method was invented whereby particulate free films of a great many substances can be deposited by pulsed laser deposition.
