摘要：
A lubricant containing a fluorinated dicarboxylic acid of the formula: A.sup.1 --COO--R.sup.1 --Rf--R.sup.2 --OCO--A.sup.2 in which Rf is a divalent perfluoropolyether group; R.sup.1 and R.sup.2 are the same or different and represent a hydrocarbon group; and A.sup.1 and A.sup.2 are the same or different and represent an organic group having a carboxyl group, which allows two solid materials, for example, a magnetic recording medium and a magnetic head, to slide with low wearing at a low friction under various conditions.
