  The isothermal entropy change and the adiabatic temperature change for the
exactly solved spin-1/2 Fisher's super-exchange antiferromagnet are rigorously
calculated in order to examine magnetocaloric properties of the model in a
vicinity of the second-order phase transition. It is shown that the large
inverse magnetocaloric effect occurs around the temperature interval
$T_c(h\neq0) < T < T_c(h=0)$ for any magnetic-field change $\Delta h: 0 \to h$.
The most pronounced inverse magnetocaloric effect can be found for the
magnetic-field change, which coincides with the critical field of a
zero-temperature phase transition from the antiferromagnetically ordered ground
state to the paramagnetic one.
