dc.description.abstract | The low-temperature phase of single crystals of Nd0.5Ca0.5MnO3 and Gd0.5Ca0.5MnO3 manganites is investigated by superconducting quantum interference device magnetometry. Nd0.5Ca0.5MnO3 undergoes a charge-ordering transition at T-CO=245 K, and a long-range charge-exchange-type (CE-type) antiferromagnetic state is established at T-N=145 K. The dc magnetization shows a cooling-rate dependence below T-N, associated with a weak spontaneous moment. The associated excess magnetization is related to uncompensated spins in the CE-type antiferromagnetic structure and to the presence in this state of fully orbital ordered regions separated by orbital domain walls. The observed cooling rate dependence is interpreted to be a consequence of the rearrangement of the orbital domain state induced by the large structural changes occurring upon cooling. | en_US |
