Frustrated antiferromagnets and role of dzyaloshinskii moriya interaction

Abstract

In this thesis we have extensively worked on the nature of the ground state of different frustrated magnets especially on kagome lattice and the possible magnetic long range order state in those systems Due to low dimensionality a higher degree of frustration and larger quantum fluctuations makes kagome Heisenberg antiferromagnet KHAF a suitable candidate to host a quantum spin liquid ground state In the isotropic case i e in the absence of DMI the ground state of kagome Heisenberg...
