The metamagnetic jumps exist in the magnetization process at the higher edge of the 1/3 and 2/3 plateaus. The parameter-dependencies of the critical field and the magnitude of the magnetization jump at the higher edge of the 1/3 plateau are obtained by using the approximated state in the unit cell and compared wth numerical results of the exact diagonalization of 42 sites.}, pages = {014404-1--014404-9}, title = {Metamagnetic jump in the spin-1/2 antiferromagnetic Heisenberg model on the square kagome lattice}, volume = {98}, year = {2018} }
