We present the results of magnetization measurements on single-crystal holmium using a SQUID magnetometer in the temperature range from 4.2 to 140 K in magnetic fields from 0.01 to 3 T applied along the {ital b} axis. Our magnetization data shows the Neel temperature to be {ital T}{sub {ital N}}=132 K. In addition, we observe anomalies in the temperature dependence of the magnetization at 21, 42, and 98 K. These anomalies can be accounted for within the spin-slip model; Bohr {ital et} {ital al}. (Physica (Amsterdam) 140{ital A}, 349 (1986)) have pointed out the existences of ferrimagnetic structures spin slip and Cowley and Bates (J. Phys. C 21, 4113 (1988)) additional structures that breaks the hexagonal symmetry.
