A detailed structural, magnetic, and ferroelectric property of bulk polycrystalline Y_1-xZr_xCrO₃ (0 ≤ x ≤ 0.2) has been made. All the samples in the present series were made using the standard solid-state sintering technique. X-ray diffraction (XRD) data reveals that the single-phase samples can be prepared for Zr-concentration up to x = 0.1, and a systematic decrease of the lattice parameters can be observed with the increase of Zr doping at the Y-site in the present YCrO₃ system. All the samples show paramagnetic to antiferromagnetic transition around 140 K (T_N) as revealed from the temperature-dependent magnetization (M) data, and a small increase in the value of saturation magnetization (M_sat) can be seen with successive Zr-doping in the system. Interestingly, unlike YCrO₃, the M-T data measured under the zero-field cooled (ZFC) condition shows negative M value for both the Zr-doped samples in the present series below T_N. A notable enhancement of both critical field (H_C) and remnant magnetization (M_r) is observed for the Zr-doped samples compared with the pristine YCrO₃ sample measured under similar conditions. Polarization-electric field (P-E) hysteresis behavior of undoped and Zr-doped samples is measured at low temperature to reduce leakage current contribution, show an enhancement of remnant polarization (P_r) with successive Zr doping within YCrO₃, indicating a better bifferoic nature in Zr-doped sample in the present study.

Zr掺杂Y 1-x Zr x CrO 3本体多晶体系的结构，磁性和铁电性质

详细的散装的多晶结构，磁性，和铁电性能ÿ _{1- X}的Zr _X的CrO ₃（0≤  X  ≤0.2）已经取得进展。本系列中的所有样品均使用标准固态烧结技术制成。X射线衍射（XRD）数据表明，可以制备Zr浓度高达x  = 0.1的单相样品，并且随着Y位置Zr掺杂的增加，可以观察到晶格参数的系统性降低在目前的YCrO ₃系统中。所有样品在140 K（T _N）附近均表现出顺磁至反铁磁转变，这与温度相关的磁化强度（M）数据，以及在系统中连续进行Zr掺杂后，可以看到饱和磁化强度（M _sat）的小幅增加。有趣的是，与YCrO ₃不同，在零场冷却（ZFC）条件下测得的MT数据在T _N以下显示了本系列中两个掺Zr样品的负M值。与原始的YCrO ₃相比，掺Zr的样品的临界场（H _C）和剩余磁化强度（M _r）都有显着提高。样品在类似条件下测量。在低温下测量未掺杂样品和Zr掺杂样品的极化电场（PE）磁滞行为，以减少泄漏电流的影响，显示出残余极化（P _r）的增强，YCrO ₃内连续进行Zr掺杂，表明具有更好的二流性质本研究中掺杂Zr的样品
