摘要：

A method is described for preparing samples of magnetic lacquers for transmission electron microscopy. The samples contain only the permanent aggregates present in a suspension, and not the temporary agglomerates that are easily broken up when the suspension is sheared. The method is based on a dilution of the material studied with other magnetic particles, that are dissolved after a thin film of the mixed suspension is deposited on a carbon substrate film. Using this method, it is shown that most of the chromium dioxide in a well-dispersed lacquer occurs in parallel aggregates of 2–10 particles, that were never separated. The formation of new, lasting aggregates in the lacquer was found to take place only in the course of days. © 1990 IEEE
