摘要: Abstract We report the low temperature magnetic structure of Ho 2 CoGa 8 intermetallic compound studied by X-ray scattering technique at Brazilian Synchrotron Light Laboratory. found that below T N = 5.1 K , has a commensurate antiferromagnetic with propagation vector η ⇒ ( 1 ) and preliminary analysis indicated moment points along c -axis. The this was obtained measuring strong dipolar resonant peak L 3 edge using polarization analysis. properties are to be consistent general trend already seen for Nd-, Tb-, Ce-based compounds from R m M n In + family (R=rare earth; M=Co, Rh, or Ir; ; 0 ).
