Heat Capacity in Pulsed Fields

Quite often, heat capacity measurements conducted in high magnetic fields are combined with measurements of the magnetocaloric effect (MCE).

Heat capacity is the ratio of the heat added to (or subtracted from) an object to the resulting temperature change. The SI unit of heat capacity is joule per degree kelvin. Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, so that the quantity is independent of the size or extent of the sample. The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance. The specific heat capacity, often simply called specific heat, is the heat capacity per unit mass of a material.
