12 May 2005 | | Subject: | Materials Science; Superconductivity | cond-mat.mtrl-sci cond-mat.supr-con | | Abstract: | Using density-functional-based methods, we have studied the effects of incipient magnetism in the cubic perovskites MgCNi_{3} and YBRh_{3} . Our results show that (i) at the equilibrium volume, both MgCNi_{3} and YBRh_{3} alloys remain paramagnetic and (ii) at expanded volumes, only YBRh_{3} shows the possibility of a ferromagnetic phase with a local magnetic moment larger than 0.25 mu_{B} per Rh atom. | | Source: | arXiv, cond-mat/0505310 | | Services: | Forum | Review | PDF | Favorites | |
