Properties of magnets of type (Nd, Pr, R)(2)(Fe, Co, M)(14)B are studied in a wide temperature range after different variants of heat treatment. The inflections on the demagnetization curves are associated with defects on the surface of the small-size test pieces. An additional inflection on the demagnetization curve at 10 - 20 K is associated with the presence of a R-1.1(Fe, Co)(4)B-4 ferromagnetic phase in the studied temperature range.
