A method for direct measurement of the magnetocaloric effect (MCE) in alternating magnetic fields is offered. Main advantages of the method compared to a classical direct one are the high temperature sensitivity (better than 10-3 K); the…

The excellent magnetocaloric effect of a dense inorganic framework, orthorhombic Gd(OH)CO3, is evaluated by isothermal magnetization and heat capacity measurements. The large -{\Delta}Sm, both in gravimetric and volumetric units, place it…

Caloric responses (temperature changes) can be induced in solid-state materials by applying external stimuli such as stress, pressure, and electric and magnetic fields. The magnetic-field-stimulated response is called the magnetocaloric…
