SOME ASPECTS OF RECENT IMPROVEMENTS OF TEMPERATURE-MODULATED CALORIMETER

Some aspects of recent improvements in temperature modulated calorimet er have been described. The contents are: (1) a low-frequency AC calor imeter with an improved resolution; delta C-p/C-p congruent to 0.010%, delta T similar to 7 mK; (2) an ultra-low frequency fully automated m ultifrequency AC calorimeter operated down to 0.5 mHz; and (3) a calor imeter with a capability of both AC-mode and relaxation-mode operation s.
