Spinon signatures in the critical phase of the (1,1/2) ferrimagnet in a magnetic field
A. K. Kolezhuk, H. -J. Mikeska, K. Maisinger +1
We propose an effective theory for the critical phase of a quantum ferrimagnetic chain with alternating spins 1 and 1/2 in an external magnetic field. With the help of the matrix p…
Combination of Ferromagnetic and Antiferromagnetic Features in Heisenberg Ferrimagnets
Shoji Yamamoto, Takahiro Fukui, Klaus Maisinger +1
We investigate the thermodynamic properties of Heisenberg ferrimagnetic mixed-spin chains both numerically and analytically with particular emphasis on the combination of ferromagn…
Thermodynamics of the (1,1/2) Ferrimagnet in Finite Magnetic Fields
K. Maisinger, U. Schollwoeck, S. Brehmer +2
We investigate the specific heat and magnetisation of a ferrimagnet with gS=1 and S=1/2 spins in a finite magnetic field using the transfer matrix DMRG down to T=0.025J. Ferromagne…
Thermodynamics of frustrated quantum spin chains
K. Maisinger, U. Schollwoeck
We apply the transfer matrix DMRG to frustrated quantum spin chains, going down to T=0.025 while being in the thermodynamic limit. The incommensurability problem of exact diagonali…
