Implication

Theoretical modeling reveals field-induced collinear spin ordering in highly frustrated antiferromagnets, indicating the formation of thermal-fluctuation-stabilized magnetization plateaus.

Key Points

Investigate whether external magnetic fields and thermal fluctuations can induce collinear spin ordering and magnetization plateaus in highly frustrated Heisenberg antiferromagnets.
Derived analytical predictions for spin stabilization across kagome, garnet, pyrochlore, and frustrated square lattices.
Conducted classical Monte Carlo simulations and quantum S = 1/2 exact diagonalization on frustrated square-lattice antiferromagnets.
Analytically established that thermal fluctuations stabilize collinear states at one-third of the saturation field for kagome and garnet lattices, and at one-half of the saturation field for pyrochlore and square lattices.
Demonstrated numerically that these field-induced collinear states exhibit an energy spin gap and yield distinct magnetization plateaus.
