“…The above results of magnetic susceptibility, heat capacity, and pulsed-high-field magnetization measurements have confirmed that Co 3 (SeO 3 )(SO 4 )(OH) 2 possesses a canted AFM ordering at low temperature, while three successive metamagnetic transitions can be induced by external magnetic field up to 53 T. We noted that such successive metamagnetic transitions are also observed in zigzag-chain system Co 2 V 2 O 7 and kagomé staircase compound Co 3 V 2 O 8 with multiple exchange interactions. Considering the coupling angles and spin frustration, a possible spin arrangement is suggested in the kagomé layers (Figure b).…”

“…Interestingly, the kagomé layers of Co 3 (SeO 3 )(SO 4 )(OH) 2 can also be considered as two weak FM chains with an AF interaction exchange. As seen in many CoO-based chain compounds including CoV 2 O 6 , CoNb 2 O 6 , and Co 2 V 2 O 7, a competition between AFM and FM interaction exchanges may result in such field-induced metamagnetic transitions. To further understand the nature of magnetic behaviors of Co 3 (SeO 3 )(SO 4 )(OH) 2 , such experiments including NMR, ESR, and neutron scattering may be carried out in the future.…”

Co₃(SeO₃)(SO₄)(OH)₂: A Selenite-Sulfate Compound with a Distorted Kagomé Lattice

et al. 2020

A new selenite-sulfate compound Co 3 (SeO 3 )(SO 4 )-(OH) 2 was prepared using a typical hydrothermal reaction. This compound is found to crystallize in an orthorhombic space group of Pnma, featuring a 2D distorted kagoméstructure composed of linear and zigzag Co-chains, in which the magnetic ions construct different isosceles-triangles. Our results of magnetic and specific heat measurements confirm a canted antiferromagnetic order at T N ∼ 29 K. Further, the successive field-induced metamagnetic transitions can be observed at H c1 ∼ 1 T, H c2 ∼ 23 T, and H c3 ∼ 27 T, respectively. A clear magnetic hysteresis loop with a coercive field (H c ) of ∼1.4 T is also observed.

“…A formation of a distorted honeycomb lattice is also seen in the Mn 2 V 2 O 7 pyrovanadate, where intriguing coexistence of ferroelastic and antiferromagnetic ordering was reported [16,32]. On the other hand, bond-alternating skew chains form in Co 2 V 2 O 7 , in which the magnetic-field-induced magnetization plateau, possibly related to the ferroelectricity, was observed [8,10,11,14,15].…”

Magnetic properties of the pyrovanadate CaCoV2O7 have been studied by means of the bulk magnetization and neutron powder diffraction measurements. Magnetic susceptibility in the paramagnetic phase shows Curie-Weiss behavior with negative Weiss temperature Θ ≃ −22.5 K, indicating dominant antiferromagnetic interactions. At TN = 3.44 K, CaCoV2O7 shows antiferromagnetic order, accompanied by a weak net ferromagnetic moment of ∼ 0.05 µB/Co 2+ . Neutron powder diffraction confirms the formation of antiferromagnetic order below TN. It was further confirmed from the magnetic structure determination that the two Co 2+ ions in the adjacent edge-sharing octahedra have almost parallel (ferromagnetic) spin arrangement, indicative of a formation of a ferromagnetic spin dimer. The antiferromagnetic order is, in turn, stabilized by sizable inter-dimer antiferromagnetic interactions.

“…Low-dimensional spin systems have been attracting a lot of attention in condensed matter physics due to their exotic ground states and non-classical effects caused by spin fluctuation and magnetic frustration [1][2][3][4]. In particular, the transition metal pyrovanadate compounds have been extensively studied, and these systems exhibit complicated and intriguing physical properties, such as field-induced spin-flop-like transition [5,6], magnetization plateau [7], magnetoelectric coupling [8], and magnetic-field induced ferroelectric behavior [9].…”

High Magnetic Field ESR in S = 1 Skew Chain Antiferromagnet Ni2V2O7 Single Crystal

et al. 2019

View full text Add to dashboard Cite

We report electron spin resonance (ESR) in S = 1 skew chain antiferromagnet Ni2V2O7, which exhibits a spin-flop transition and a well-defined 1/2 magnetization plateau. The antiferromagnetic (AFM) ordering at TN = 7 K can be reflected by the temperature-dependent ESR spectra at low frequency for the easy axis. At 2 K, at the spin-flop transition fields along the easy a and b axes, anomalies are observed from the frequency‒field relationship. However, these modes cannot be understood by the conventional two-sublattice AFM resonance theory with uniaxial anisotropy. For the easy b axis, an unusual resonance mode is observed and its resonance field increases with decreasing frequency. This ESR mode becomes softening at ~8 T, corresponding to the onset of the 1/2 magnetization plateau.
