Notes:
La0.55Er0.05Ca0.4MnO3 in bulk form was prepared both by solid-state reaction and by a sol–gel method. Samples prepared by both methods showed a moderate magnetic entropy change near its Curie temperature, this spread to a large temperature span upon the application of a magnetic field of 1.8 T. The material prepared by the sol–gel method exhibits a large magnetoresistance below its Curie temperature, which is considered to result from the interfacial spin-dependent tunneling. © 1998 American Institute of Physics.
