We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT)
correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk …

Thermal fluctuations in magnetizations and magnetic phase diagrams of a diatomic
molecule are investigated on the Bethe lattice (BL) with coordination number\(q= 3\) by …

We examine the thermal properties of the spin-1 Heisenberg antiferromagnet on the
honeycomb lattice in the presence of an easy-plane single-ion anisotropy as well as the …

The growth of sufficiently large single crystals of Cu (tn) Cl 2 (tn= 1, 3-diaminopropane)
enabled specific heat and susceptibility studies in various field orientations. The nearly …

Materials realizing the XY model in two dimensions are sparse. Here we use neutron triple-
axis spectroscopy to investigate the critical static and dynamical magnetic fluctuations in the …

In two-dimensional (2D) spin systems, the augmentation of spin fluctuations gives rise to
quasi-long-range order; however, how they manifest in spin transport remains unclear. Here …

We present an overview of selected copper-based quasi-2D square-lattice spin-1/2
materials with an easy-plane anisotropy, providing the possibility to study emergent …

In this thesis, we study different quantum Heisenberg antiferromagnets (AFMs) by means of
unbiased large-scale quantum Monte Carlo (QMC) simulations. First, we consider the spin-1 …

In this report, we compare the analysis of electron spin resonance (ESR) studies of
Berezinskii-Kosterlitz-Thouless (BKT) correlations in the spin S= 1 Ni 2+-based layered …

In this work, we use high-resolution neutron Triple-Axis and Spin-echo spectroscopy to study
the critical properties of the strongly electron-correlated 4d square-lattice antiferromagnets …
