An innovative nanocalorimeter has been developed for measuring specific
heats of thin films, multilayers (typical thickness: 1000 �) and
single crystals (mass: 1 �g) in the temperature range of 1.5�20 K.
The addenda of the device are as small as 3 nJ/K at 4 K (0.5 nJ/K
at 1.5 K), thus samples with a heat capacity of the order of nJ/K
at 4 K can be measured. Heat capacity differences as a function of
temperature or an external magnetic field (5 T) were determined with
a resolution of Delta C/C ~= 10�4. This way we have seen heat capacity
variations of less than a pJ/K. We present as an example measurements
on very small Mn12O12 acetate single crystals and a measurement of
a thin superconducting Pb layer. In the latter measurement we could
evidence via specific heat a finite size effect.
