Quantu features of two types of Dzyaloshinskii-Moriya coupling in antiferromagnetic spin chain
A ID spin quantum system (S = 1/2) with the Dzyaloshinskii-Moriya interaction is studied. It is shown that this type of coupling in the antiferromagnetic chain with an odd structure with respect to the main axis accounts for a staggered magnetic ordering in the ground state. For an even structure t...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A ID spin quantum system (S = 1/2) with the Dzyaloshinskii-Moriya interaction is studied. It is shown that this type of coupling in the antiferromagnetic chain with an odd structure with respect to the main axis accounts for a staggered magnetic ordering in the ground state. For an even structure the Dzyaloshinskii-Moriya interaction causes a helicoidal spin structure only. Correlation functions are calculated under different conditions. |
