Deciphering role of the Fe substitution in modulating the structural, magnetic and magnetocaloric properties of $\mathrm{NdCrTi_{5}}$

Abstract

A detailed magnetic study on the Fe substituted $\mathrm{NdCrTi_{5}}$is presented. Phase purity of polycrystalline $\mathrm{NdCr_{0.5}Fe_{0.5}TiO_5}$ 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 $T_N  ∼$ 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 (at 5 K) indicate the presence of weak ferromagnetism
