Analysis of Incommensurate Magnetic Structures of Rare-Earth Intermetallides Tb3Ni and Ho7Rh3 Using the Magnetic Supersymmetry Group Formalism

Аннотация

Complex incommensurate magnetic structures of Tb₃Ni and Ho₇Rh₃ compounds have been analyzed using the magnetic superspace group approach. It has been established that the high-temperature incommensurate magnetic structure of Tb₃Ni is described by the magnetic superspace group P112₁/a1'(ab0)0ss and the incommensurate magnetic structure of Ho₇Rh₃ is described by the magnetic superspace group \(P{{6}_{3}}1{\kern 1pt} '\left( {00g} \right)hs.\) Using the example of the Tb₃Ni and Ho₇Rh₃ compounds, it is shown that the magnetic superspace groups formalism is the most efficient approach when establishing and describing complex incommensurate magnetic structures.
