Anomalous magnetization process in frustrated spin ladders
نویسندگان
چکیده
We study, at T = 0, the anomalies in the magnetization curve of the S = 1 two-leg ladder with frustrated interactions. We focus mainly on the existence of the M = Ms/2 plateau, where Ms is the saturation magnetization. We reports the results by degenerate perturbation theory and and the density matrix renormalization group, which lead to the consistent conclusion with each other. We also touch on the M = Ms/4 and M = (3/4)Ms plateaux and cusps. PACS numbers: 75.10.Jm, 75.40.Cx, 75.50.Ee, 75.50.Gg Anomalous magnetization process in frustrated spin ladders 2

Magnetization plateaux and jumps in a class of frustrated ladders: A simple route to a complex behaviour
We study the occurrence of plateaux and jumps in the magnetization curves of a class of frustrated ladders for which the Hamiltonian can be written in terms of the total spin of a rung. We argue on the basis of exact diagonalization of finite clusters that the ground state energy as a function of magnetization can be obtained as the minimum with Maxwell constructions if necessary of the energie...
متن کاملMagnetization plateaus in frustrated antiferromagnetic quantum spin models
Plateaus can be observed in the zero-temperature magnetization curve of quantum spin systems at rational values of the magnetization. In one dimension, the appearance of a plateau is controlled by a quantization condition for the magnetization which involves the length of the local spin and the volume of a translational unit cell of the ground state. We discuss examples of geometrically frustra...
متن کاملMultiple frustration-induced plateaus in a magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain
Abstract. Magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain is examined by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method. Multiple frustrationinduced plateaus in a magnetization process of this geometrically frustrated system are found provided that a relative ratio betwe...
متن کاملLadders in a magnetic field: a strong coupling approach
We show that non-frustrated and frustrated ladders in a magnetic field can be systematically mapped onto an XXZ Heisenberg model in a longitudinal magnetic field in the limit where the rung coupling is the dominant one. This mapping is valid in the critical region where the magnetization goes from zero to saturation. It allows one to relate the properties of the critical phase (H c , H 2 c , th...
متن کاملUltra-robust high-field magnetization plateau and supersolidity in bond-frustrated MnCr2S4
Frustrated magnets provide a promising avenue for realizing exotic quantum states of matter, such as spin liquids and spin ice or complex spin molecules. Under an external magnetic field, frustrated magnets can exhibit fractional magnetization plateaus related to definite spin patterns stabilized by field-induced lattice distortions. Magnetization and ultrasound experiments in MnCr2S4 up to 60 ...
