Abstract: | Summary We have investigated the Aharonov-Bohm (AB) effects of electronic thermal capacityC
v
in a one-dimensional normal ring using the free-electron model. The results show that the thermal capacity is an oscillation
function of external magnetic flux with periods ϕ0=hc/e, ϕ0/2, ϕ0/3,... The amplitude of the capacity fluctuation decreases when temperature increases forT>3T
