In the previous work this system was revealed to exhibit the 1/3 magnetization plateau due to two different mechanisms depending on the coupling parameters, and the phase diagram at the 1/3 magnetization was obtained. In the present work it is found that the 1/3 magnetization plateau vanishes for sufficiently large XY-like coupling anisotropy. The phase diagram based on the level spectroscopy analysis is also presented.}, pages = {011085-1--011085-5}, title = {Magnetization Plateau of the Distorted Diamond Spin Chain}, volume = {30}, year = {2020} }
