Reducing the film thickness leads to a significant suppression of ferromagnetic (FM) ordering and the Curie point falls below the antiferromagnetic (AFM) transition temperature. When this occurs, a huge rise of the magnetoresistance ratio from 400 to 60?000% is observed in an applied magnetic field of 5 T. We surmise that this new kind of the enhanced colossal magnetoresistance effect originates in the FM/AFM competition and the collapse of the charge-ordered state at high magnetic fields, rather than in the regular double-exchange mechanism.","charge-ordered states; colossal magnetoresistance; Curie temperature; magnetic epitaxial layers; metal-insulator transition; neodymium compounds; sputter deposition; strontium compounds","en","journal article","American Institute of Physics","","","","","","","","Applied Sciences","","","","",""
