Abstract
Multiferroics have received considerable interest over the last decade due to the fascinating fundamental phenomena and potential use in various applications, such as low-power electronics and spintronics. Among those, investigations have focused on the coexistence of ferroelectric and ferromagnetic mate-rials. Here, we report the rare case that the para-to ferroelastic ordering transition in antiferromagnet Mn2V2O7 occurred at T-S = 260-280 K, verified by temperature-dependent magnetization measurements, dielectric, differential scanning calorimetry, and macroscopic strain-stress hysteresis loops. Furthermore, this transition was accompanied by a structural transition from the high-temperature C2/m monoclinic phase (beta-phase) to a low-temperature P (1) over bar triclinic phase (alpha-phase), as identified by temperature-dependent X-ray diffraction. Consequently, T-S can be successfully increased by Co-and Ni-doping and decreased by Ca-doping. Thus, the phase diagram was established for the structural stability of (Mn(1-x)A(x))(2)V2O7 (A = Co, Ni, and Ca). In addition, the physical and chemical pressure effects were applied on (Mn(1-x)C(a)x)(2)V2O7 to correlate the ferroelastic (TS) and antiferromagnetic (TN) orderings. Consequently, the magnetoelastic coupling was revealed, and a unique multiferroic material (Mn2V2O7) with a fer-roelastic and antiferromagnetic ordering was obtained. (C) 2022 Elsevier Ltd.
