LOW TEMPERATURE BEHAVIOUR OF HoBi.

Article abstract of DOI:10.1016/0022-5088(84)90203-0

Low-temperature measurements indicate that HoBi undergoes a first-order transition to a pseudotetragonal antiferromagnetic structure at T//N equals 5. 72 K. The gross features of HoBi are similar to those of HoSb, and its behavior also appears to be close to tricritical. Unlike HoSb, however, which contracts in the C direction at T//N, its axial ratio c/a is greater than unity. Moreover, the magnetic-field-induced transitions in HoBi occur in stages which strongly depend on the external stress and the magnetic history.
