Magnetocaloric and magnetoresistance properties of La2/3Sr1/3Mn1−xCoxO3 compounds
چکیده انگلیسی

Structural, magnetic, magnetoresistance and magnetocaloric studies on La2/3Sr1/3Mn1−xCoxO3 compounds were reported. The samples were prepared by the conventional ceramic method. X-ray analysis showed the presence of one phase only, in all studied samples. From electrical resistance measurements it was found that the samples show large negative magnetoresistance behavior. The magnetic measurements were performed in a large temperature range, 4.2–750 K and external magnetic fields up to 5 T. The adiabatic magnetic entropy changes, |ΔS|, were determined from magnetization data. Large magnetocaloric effect (MCE) has been obtained in all studied samples.
