the magnetocaloric effect , _ i.e. _ , a temperature change induced by an adiabatic change of an external magnetic field was discovered in iron by warburg in 1881 @xcite . this effect also has a long history in cooling applications . for example , adiabatic demagnetization of paramagnetic salts was the first meth...

we compute the entropy of antiferromagnetic quantum spin-@xmath0 chains in an external magnetic field using exact diagonalization and quantum monte carlo simulations . the magnetocaloric effect , _ i.e. _ , temperature variations during adiabatic field changes , can be derived from the isentropes . first , we focus...
