Deciphering role of the Fe substitution in modulating the structural, magnetic and magnetocaloric properties of NdCrTiO_5

摘要

A detailed magnetic study on the Fe substituted NdCrTiO5 is presented. Phase purity of polycrystalline NdCr0.5Fe0.5TiO5 prepared by conventional solid-state technique has been confirmed by synchrotron X-ray diffraction (SXRD). Temperature-dependent magnetization (MT) measurements indicate a transition to an antiferromagnetic (AFM) type of magnetic ordering at T-N similar to 10 K. AFM type of order is also supported by magnetocaloric data. Magnetic hysteresis as well as a type of magnetic relaxation behavior collected below T-N (at 5 K) indicate the presence of weak ferromagnetism.
