“…The magnetization first reaches a maximum near 150 K and decreases to a minimum near 50 K, followed by a further increase with the decrease of temperature for the two field directions. The magnetization behavior below 150 K is complicated for the VOCl flakes, which is similar to the observations reported previously [47][48][49][50]. To gain more insights into magnetization, temperature dependent reciprocal magnetic susceptibility 1/χ is fitted with the theoretical Curie-Weiss law expressed below, It can also be clearly noticed that the deviation from the Curie-Weiss law appears near 150 K. Furthermore, the sign of the temperature dependent magnetization shows a very similar behavior to the Ntype ferrimagnetism [48,51] and therefore the temperature dependent reciprocal magnetic susceptibility 1/χ can be described by the Néel's expression [51],…”

We report the successful growth of square-like layered single crystals VOCl with a size of a few millimeters by chemical vapor transport method, and demonstrate that the layered crystals show good air stability and can be easily exfoliated. The atomic-resolution structure of the VOCl single crystals is consistent with the theoretical atomic models and the exfoliated VOCl flakes exhibit a uniform surface potential and a thickness-independent work function in the interval of 4–263 nm. Further magnetic measurements manifest that the VOCl crystal exhibit an N-type ferrimagnetic phase at 150 K and a compensation temperature of ~50 K. These findings not only enrich the magnetic family in layered materials but offer a platform for exploring new physics, and such study of microstructure, air stability, work function and magnetism in layered VOCl should push further the development of functionality tunable microwave devices or spintronics with all-layered materials.

“…28 As the concentration of Fe 3+ increases to 0.4, the magnetization reversal disappears and the spin reorientation phenomenon appears, indicating that the intrinsic magnetic interaction has changed. 47 In the YbFeO 3 compounds, the coupling between Yb 3+ and Fe 3+ is parallel. 45 Based on the above considerations, we assumed that the magnetic moment couplings of Yb 3+ and FM are also parallel.…”

“…where the first term symbolizes simple C-W behaviour at high-temperature region, and last term is responsible for hyperbolic behaviour near FiM ordering [48,49]. Here, Θ and ξ are the fitting parameters, and their origins have been described in the two sub-lattice model of FiM [49]. The green solid line in figure 3 is the fitted curve to χ −1 (T ) according to equation (1), and an exact fit thus establishes the FiM ordering around T = 104 K in this compound.…”

Iridium-based double perovskites having mixed 3d-5d-4 f magnetic sub-lattices are expected to exhibit exotic magnetic phenomenon. In this paper, we report a study of structural, magnetic and transport properties of the mixed 3d-5d-4 f double perovskite Sm 2 CoIrO 6 (SMCO), which crystallizes in monoclinic structure with space group P2 1 /n and the crystal symmetry remains same throughout the measured temperature down to 15 K. High resolution synchrotron x-ray diffraction reveals an isostructural phase transition around 104 K. Magnetization measurements on polycrystalline samples indicate that SMCO orders ferrimagnetically at T FiM = 104 K; while, a second transition is observed below 10 K due to the rare-earth (Sm 3+ ) ordering. The ferrimagnetic transition is well-understood by Néel's two-sublattice model, which is primarily ascribed to antiferromagnetic coupling between Co 2+ and Ir 4+ sub-lattices. Electronic transport measurement shows the insulting behaviour of SMCO, which follows Mott variable-range hopping conduction mechanism. However, dielectric measurements as a function of temperature rules out the presence of magneto dielectric coupling in this compound.
