A Study of EPR2 and Magnetic Properties at Low Temperatures

Abstract

CuCl2 • 2NC₅H₅, which is regarded as one of the best known uniform spin-1/2 Heisenberg antiferromagnetic chain systems, was studied using electron paramagnetic resonance (EPR) and neutron diffraction techniques. According to our findings, CuCl₂ • 2NC₅H₅ undergoes a magnetically ordered spiral state transition with Q = (0.5, 0.4, 0.5) r.l.u. at TN = 1.12 K, according to our findings. The zigzag interchange contacts were demonstrated to cause geometrical frustration, which influenced the ordered moment per Cu²+ and EPR characteristics, notably the angular dependency of the line width. The EPR parameters' temperature sensitivity is explored.
