Introduction The treatment of extensively distributed solid wastes generated by metallurgical processes is a challenge for the environmental sustainability of mining regions [1,2]. Antiferromagnetic coupling between two copper ions has been observed in a wide variety of dimeric Cu(II) complexes (8) and in the four-copper derivative of bovine superoxide dismutase (9). Metrics details. Despite its simplicity, the magnetic structure of copper oxalate has not been settled. When matter interacts with the magnetic field, an internal magnetization or polarization (J) is created that either opposes or augments the external field. Working off-campus? Susceptibility is a measure of the extent to which a substance becomes magnetized when it is placed in an external magnetic field. The room temperature value of the susceptibility was found to be 0.0016 emu/mol, and is corresponded to the effective magnetic moment of 1.9 μ B.

The magnetic susceptibility as a function of temperature is calculated numerically. Magnetic susceptibility is a macroscopic property that characterizes the magnetization of a material in response to an applied magnetic field ().For spatially varying susceptibility, local field perturbations arise at interfaces, such as the boundary between recording electrodes and surrounding brain tissue, resulting in distortions in MR images and spectra (2–5).
