A lubricant composition comprises a lubricant and a stabilizer. The stabilizer comprises a first epoxide group and a second functional group selected from the group consisting of (i) a second epoxide group; (ii) an aliphatic carbon-carbon multiple bond conjugated with a second carbon-carbon multiple bond; (iii) an aliphatic carbon-carbon multiple bond conjugated with an electron withdrawing group; and (iv) an aliphatic carbon-carbon multiple bond conjugated with an aromatic group. A heat transfer composition comprises a lubricant composition as described above and a haloalkane, such as an iodoalkane (e.g., trifluoroiodomethane).

Fluoropolyether compounds that can be used as a lubricant, such as for magnetic recording media. The compounds have a terminal group that includes a phenol or benzene. The fluoropolyether compounds reduce the head to media distance while keeping comparable reliability in a hard disk drive compared to current industrial widely used fluoropolyether based lubricants.
