Abstract

We prepared single crystals in UCo_1−xRh_xGe and UIr_1−xRh_xGe systems to establish a complex d_U-U-T (d_U-U is the shortest interatomic uranium distance and T is temperature) magnetic phase diagram. This recognized a characteristic maximum in magnetic susceptibility at temperature T_max along the b axis as an important parameter. Three magnetically ordered regions can be distinguished within this scope; first a ferromagnetic region with Curie temperature<T_max, second a ferromagnetic region with Curie temperature ≈ T_max and finally an antiferromagnetic region existing on the UIrGe side with Néel temperature<T_max.
