Reversals of magnetization and exchange-bias in perovskite chromite YbCrO3

Magnetic Domain-Wall Induced Electric Polarization in NdCrO3 Polycrystalline Ceramic

“…Figure 2 shows the zero-field-cooled (ZFC) and field-cooled (FC) temperature-dependent dc magnetization from 5 K to 320 K under a measuring field of 100 Oe. Two magnetic transitions, TN and TSR, occurred at about 227 K and 38 K, respectively, which were consistent with previous studies [22,[24][25][26] and their magnetic behavior could be explained by the strong effective field on the Nd 3+ moments exerted by the ordered Cr 3+ spin system [27,28]. The first transition temperature TN (227 K) corresponded to canted AFM transition of the Cr 3+ magnetic moments and the system showed a weak ferromagnetism.…”

Reversals of magnetization and exchange-bias in perovskite chromite TmCrO3

“…Figure 3( were just in the opposite directions compared to those in FC mode [11]. The disappeared magnetization reversal in Figure 2 (b) indicates that when the cooling field increases to 10 kOe (exceeds the negative internal field), the Tm 3+ moment will flip to the direction of the external field [11,12]. As reported earlier, the minimum value of magnetization (at ~10 K)…”

“…Interestingly, magnetization reversal and EB reversal were observed together frequently [8,9]. In our previous work [12], we have highlighted the intrinsic association of the two reversals, and the explanation model in YbCrO3 can also be applicable to TmCrO3.…”

The tunable spin reorientation, temperature induced magnetization reversal, and spontaneous exchange bias effect of Sm0.7Y0.3Cr1−xGaxO3

“…Most reported TIMR effect from positive to negative occurs in FC mode while few in ZFC mode. 2,10,25,[38][39][40][41][42] Here, the TIMR effect observed in ZFC mode shows dependence on doping concentration and the compensation temperature for x ¼ 0.2 and 0.3 is at near 74 K and almost the same, indicating its intrinsic feature.…”
