The invention provides a method of treating a material to cause the material to evolve from one phase to a more ordered phase, the method comprising an operation of irradiating the material in which the irradiating particles are suitable, by their nature and by their energy, for inducing displacements of the atoms in the material towards positions that favor ordering of the material. Advantageously, the invention also provides apparatus for magnetically recording information, the apparatus comprising a material deposited on a substrate at a temperature of less than 350° C. and that has been subjected to irradiation with irradiating particles that are suitable, by their nature and their energy, for inducing displacements of the atoms in the material towards positions that favor relaxation of the material.
A method of treating a material that is capable of obtaining a crystalline phase which is more ordered to cause the material to pass from a less ordered phase to the more ordered crystalline phase, the method comprising an operation of irradiating the material by light ions having an energy of 200 keV or less, the irradiation by said light ions inducing displacements of atoms in the material towards positions that favor ordering of the material to obtain the more ordered crystalline phase, wherein said light ions are ions having a mass below or equal to 16 atomic mass units, the method further comprising an operation of simultaneous heating the material, during the irradiation, at temperature of 350° C. or less.
