Description
The specific heat of a single crystal of the layered perovskite La1.2Sr1.8Mn2O7 has been measured for 83<T<290 K. A high, narrow peak associated with the ferromagnetic ordering of the Mn3+-Mn4+ ions is observed to have a maximum at Tc=115.57 K, in agreement with magnetization, neutron scattering, and resistivity measurements. A second, hysteretic, peak at 260 K is also observed. An estimate is made of the substantial magnetic entropy removed by cooling the crystal from 290 K to Tc. copyright 1999 The American Physical Society
