Excitation of 2D Majorana Fermions in Two Chiral States of a Quantum Spin Liquid in La0.15Sm0.85MnO3+delta Manganites Controlled by External Magnetic Field

In this work, we investigated the evolution of the low-energy spinonpairs' excitation in the first Landau zone in frustrated La 0.15 Sm 0.85 MnO 3 manganites, caused by changes in the strength H of the measuring field.In samples La 0.15 Sm 0.85 MnO 3 , an alternation of spiky double-peaks and truncated-hill-features of 'supermagnetization' M(T), characteristic of two types of excitation of 2D Majorana fermions in hidden topological states CSL1 and CSL2 of quantum chiral spin liquid (CSL), was detected.
