초록/요약
Comprehensive measurements of electron spin resonance (ESR) and magnetization of La0:7Ca0:3MnO 3 in the ferromagnetic aswell as paramagnetic phases were carried out. Quantitative evidences for the inhomogeneous magnetic structure, consisting offerromagnetic microregions embedded in the antiferromagnetic surrounding nearTc, were found. It is suggested that the microscopiclocal magnetic structures above and belowTc are qualitatively similar except that the phase belowTc carries long range orderbetween the ferromagnetic microregions whose sizes grow with decreasing temperature.. 2002 Elsevier Science B.V.
