  • Abstract
A tip for FIM was made of various kinds of metals in order to monitor the tip temperature. A conventional four‐terminal method was used to measure the average temperature of the loop at the instant the tip melted. A computer calculation has also been carried out to obtain the temperature distribution in the loop and tip. The tip‐base temperature was obtained by matching the calculated loop resistance to the measured resistance. Finally, the calculated tip‐base temperature agreed well with the melting points of the tip materials to an accuracy of better than 99%.
