Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
124 words
A METHOD OF PRODUCING A SUBSTANTIALLY ISOTROPIC MAGNETIC DEVICE COMPRISING HEATING AT LEAST ONE SALT OF B-DIKETONE AND A MAGNETICALLY SUSCEPTIBLE METAL TO A TEMPERATURE SUFFICIENTLY HIGH TO VOLATILIZE SAID METAL SALT BUT BELOW THE TEMPERATURE AT WHICH THE VAPORS OF THE SALT DECOMPOSE, HEATING A SUBSTRATE TO A TEMPERATURE NOT BELOW 380*C. AND NOT GREATER THAN 500*C., PASSING A NONOXIDIZING CARRIER GAS OVER THE METAL SALT WHEREBY VAPORS OF THE METAL SALT ARE ADMIXED WITH THE CARRIER GAS AND CONTACTING SAID GASEOUS MIXTURE WITH THE HEATED SUBSTRATE FOR A SUFFICIENT PERIOD OF TIME TO PLATE THE SUBSTRATE WITH A COHERENT ISOTROPHIC FILM SUBSTANTIALLY FREE FROM PIN HOLES, AND APPLYING A MAGNETIC FIELD TO SAID SUBSTRATE DURING THE PLATING THEREON OF THE ISOTROPIC FILM.
