Abstract:
This study investigates the magnetoelectric (ME) effect ofz-type DyCrO4and the converse magnetoelectric (CME) effect ofs-type DyCrO4by using electron spin resonance (ESR). The peak-to-peak linewidths (ΔHpp),g-values, and double integral intensities (I) were calculated from the ESR spectra to investigate the coupling behaviors. The ME coupling effect was observed at 135 K in thez-type DyCrO4powder, evidenced by an anomaly in the temperature dependence of the intensity orgvalue extracted from ESR. The CME coupling effect was investigated ins-type DyCrO4pellet, where remarkable intensity changes on the ESR signals, induced by electric field (E), were observed below 24 K. The curves ofIversusEat 4 K, 10 K, and 15 K disclosed a temperature-dependent change in magnetization in accordance with the reported CME coupling effect. This study contributes valuable insights into the ME characteristics of DyCrO4and focuses on the potential of ESR as a powerful tool for investigating these effects in multiferroic materials.
