The study investigates the effect of Ti doping on structural, magnetic, and magnetocaloric properties of Nd-based manganites, finding that N-0.15 exhibits increased Working Temperature Span and decreased magnetic hysteresis loss, making it a potential candidate for low-temperature magnetic refrigeration.
The current study investigates the effect of Ti doping at the Mn site on structural, magnetic, and magnetocaloric properties of Nd-based manganites (Nd0.5Ca0.5TixMn1-xO3, x=0.1, 0.15 denoted as N-0.1 and N-0.15 respectively) prepared by the solid-state reaction method. N-0.1 attains maximum magnetic entropy change (-Delta S-max) 3.50Jkg(-1)K(-1) and N-0.15 attains 2.8Jkg(-1)K(-1) during magnetization. Even though Ti doping reduces the -Delta S-max value during magnetization, Working Temperature Span (WTS) increases and magnetic hysteresis loss decreases which are the desirable qualities of good magnetocaloric material and it makes N-0.15 a potential candidate for low-temperature magnetic refrigeration. Belov-Arrott plots and normalized magnetic entropy change curves suggest the existence of a field-induced first order to second order magnetic phase transition for both samples.
