“…Here, we successfully determined the saturation magnetization (M s ), magnetization remanence (M r ), and coercive field (H c ) of the respective perovskites as a function of organic chain units. We used the Langevin equation 44 to further interpret the VSM results and the fitted results are displayed in Table 2. The magnetization saturation of BA 2 CoCl 4 possesses the largest saturation and coercive field (M s = 0.160 emu/g and H c = 19.416 T) compared to the other 2D Co-HOIPs with shorter organic chain lengths.…”

Recent interest in two-dimensional (2D) lead-free hybrid organic−inorganic perovskites (HOIPs) has driven significant progress in the development of magnetic and electronic materials. Herein, we systematically compare a series of low-temperature growth of 2D cobalt-based HOIPs (Co-HOIPs) by varying the methylene chain length (n) of n = 1, 2, 3, and 4, for the first time. The Co-HOIP crystal structure with a single carbon chain displays a monoclinic arrangement with a space group of P21/c, while those with two, three, and four methylene chain lengths manifest triclinic crystal structures with a space group of P1. The optical measurements exhibit apparent odd−even effects as a function of the length of the organic ligand. The first-order phase transitions of BA 2 CoCl 4 are distinctly observed at temperatures of 12.46 and 139.77 °C compared to the shorter EA 2 CoCl 4 counterparts. Notably, this particular compound exhibits the highest magnetic saturation and coercive fields with M s = 0.160 emu/g and H c = 19.416 T, respectively. Furthermore, BA 2 CoCl 4 demonstrates superior dielectric properties, as evidenced by the shortest diameter of the equivalent circuit in EIS. These findings underscore the potential of BA 2 CoCl 4 for diverse applications in magnetic and electronic devices, highlighting its promising role in advanced technological applications.

metal ions, which play a major role in the structural distortion of doped NSDs. The magnetic studies of NSDs revealed that antiferromagnetic and ferromagnetic properties exhibited predominantly at low temperature, whereas at high-temperature, paramagnetic properties are observed. It was also found that the magnetic entropy change of NSDs at the applied magnetic field is comparatively higher, making them a suitable material for eco-friendly cryogenic systems.
