Abstract

Magnetic properties and magnetocaloric effects of the Er2TiMnO7 compound have been evaluated by magnetization and heat capacity measurements. The reversible magnetic-entropy change is found to be just above the boiling point of helium and hydrogen liquefaction temperature range of 2 to 50 K.

The magnetocaloric behavior estimated from specific heat data is confirmed by adiabatic magnetization above 2 K, and indicates that Er2TiMnO7 is a potential candidate for application in magnetic refrigeration in the low-temperature range.
