Abstract
Errors arising in the process of studying the magnetic and resistive properties of materials with the use of pulsed induction magnetometers as a result of a local nonuniformity of the magnetometer sensitivity are considered. It is shown that significant nonuniformity leads to distorted current–voltage characteristics of conducting samples and to errors in determining the critical currents of superconductors, which are not eliminated by the standard calibration procedure of magnetometers. Various designs of pickup probes for magnetometers are analyzed from the point of view of the spatial uniformity of their sensitivity, and some recommendations are given for their improvement.
