Abstract
The pseudoternary compound Ho(Ir0.7Rh0.3)4B4, which had previously been reported to exhibit the occurrence of antiferromagnetism above the superconducting transition, has been examined using heat capacity, ac magnetic susceptibility, upper critical magnetic field, thermal expansion, magnetostriction, electrical resistance, thermal conductivity, and static magnetization measurements. The data confirm the bulk nature of the antiferromagnetic phase transition and are consistent with the presence of bulk superconductivity coexisting with magnetic order.
