چکیده انگلیسی
Single phase samples of GdCr1-xMnxO3 (x=0â0.50) were prepared and their magnetic properties were studied by measuring temperature and field variations of magnetization. The Neel temperature, TN is found to decrease from TN=174Â K for x=0Â to 91Â K for x=0.50. The magnetization reversal persists upto 5Â at% of Mn substitution with a magnetic compensation temperature, Tcomp of 136Â K and 139Â K for x=0 and 0.05 respectively. However, spin reorientation induced magnetization reversal emerges for x=0.40 and 0.50 samples around 30Â K. Tunable positive and negative exchange bias fields in the range of â1.0Â kOe to +1.6Â kOe have been observed. The origin of magnetization reversal and exchange bias field is explained in terms of antiparallel alignment of canted ferromagnetic component of Cr3+ ions and the paramagnetic moments of Gd3+ and Mn3+ ions under the influence of negative internal field due to antiferromagnetically ordered Cr3+ ions.
