This relationship has yet to be confirmed. The present measurements from mixed alloys in the series CrSi/FeSi, CrSi/MnSi, CrSi/CoSi. MnSi/CoSi and CrGe/FeGe have extended the electron concentration range previously covered and the results support the suggested dependence. The q values are practically independent of temperature and the CrGe/FeGe display high Néel temperatures comparable with that of FeGe. | URI: | https://hdl.handle.net/10316/4575 | DOI: | 10.1016/S0304-8853(97)00277-1 | Rights: | openAccess |
