Abstract

Comprehensive measurements of electron spin resonance (ESR) and magnetization of La_0.7Ca_0.3MnO₃ in the ferromagnetic as well as paramagnetic phases were carried out. Quantitative evidences for the inhomogeneous magnetic structure, consisting of ferromagnetic microregions embedded in the antiferromagnetic surrounding near T_c, were found. It is suggested that the microscopic local magnetic structures above and below T_c are qualitatively similar except that the phase below T_c carries long range order between the ferromagnetic microregions whose sizes grow with decreasing temperature.
