Studies of the incommensurate structures of B20 alloys

Abstract: The B20 structure is capable of supporting a long-range antiferromagnetic static spin density wave, and for transition metal silicides and germanides it has previously been found that the N6el temperatures, high field magnetizations and magnetic propagation vectors q all suggest a dependence on an electron concentration parameter. 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… Show more

“…Likewise, early magnetization measurements and NMR in polycrystalline Mn 1−x Co x Si identified a suppression of the helimagnetic order with increasing cobalt content [82]. Subsequent small-angle neutron scattering in polycrystalline Mn 1−x Fe x Si and Mn 1−x Co x Si revealed a moderate reduction of the helical modulation length with increasing x without comparison between iron and cobalt doping [78,79].…”

“…The helimagnetic transition temperature in cubic chiral magnets responds sensitively to substitutional doping [78,79]. In turn, compositional changes represent an important tool when trying to identify the microscopic origin of the hierarchy of energy scales and the effects of fluctuations in cubic chiral magnets.…”

“…Doping with iron, cobalt, and nickel leads to an essentially identical modification of the magnetic behavior if scaled by the number valance electrons per formula unit75,89 . Doping with chromium, i.e., reducing the number of valance electrons, leads to a suppression of T c comparable to iron doping90 . This behavior is consistent with the notion that the main effects of chemical doping are due to a rigid shift the Fermi level, as recently inferred from a combined study of ab initio calculations and the electric transport properties in Mn 1−x Fe x Si ?…”
