We present the investigation of a monoclinic compound SeCuO3 using x-ray powder diffraction, magnetization, torque, and electron-spin-resonance. Structurally based analysis suggests that SeCuO3 can be considered as a three-dimensional network of tetramers. The values of intratetramer exchange interactions are extracted from the temperature dependence of the susceptibility and amount to ∼200 K. The intertetramer coupling leads to the development of long-range antiferromagnetic order at TN=8 K… 

Magnetic properties of the antiferromagnetic spin-12 tetramer compound CuInVO5

We measured the temperature dependence of the magnetic susceptibility and specific heat and the magnetic-field dependence of the magnetization of CuInVO5. An antiferromagnetically ordered state

Magnetism of the antiferromagnetic spin-1/2 tetramer compound CuInVO 5

Unconventional field induced phases in a quantum magnet formed by free radical tetramers

We report experimental and theoretical studies on the magnetic and thermodynamic properties of NIT-2Py, a free radical based organic magnet. From magnetization and specific-heat measurements we

Magnetoelectric Multiferroicity and Magnetic Anisotropy in Guanidinium Copper(II) Formate Crystal

In versatile measurements of magnetization of a crystal, including transverse component besides the longitudinal one, very large anisotropy is found that might originate from canting of the coordination octahedra around copper (II) in cooperation with the canted AFM order.

Critical spin- 12 tetramer compound CuInVO5 : Exploring the vicinity of two multimerized singlet states

Using the density-matrix renormalization group technique, we study a one-dimensional spin-1/2 Heisenberg chain consisting of coupled tetramers as an effective spin model for the copper vanadate

Strong decoupling between magnetic subsystems in the low-dimensional spin- 12 antiferromagnet SeCuO3

The search for and understanding of low-dimensional magnetic materials is essential for both fundamental and technological purposes. Here we propose a combined experimental and theoretical

Triplons, magnons, and spinons in a single quantum spin system: SeCuO3

Quantum magnets display a wide variety of collective excitations, including spin waves (magnons), coherent singlet-triplet excitations (triplons), and pairs of fractional spins (spinons). These modes

Singlet state formation and its impact on the magnetic structure in the tetramer system SeCuO3

We present an experimental investigation of the magnetic structure in a tetramer system SeCuO3 using neutron powder-diffraction and nuclear resonance
