Electron spin resonance study of Y 1-xCa xMnO 3
Abstract
ESR spectra were measured in the series Y 1-xCa xMnO 3 (YCa) (0⩽ x⩽1) obtaining the dependences with x and T. Anomalies detected in the ESR parameters (resonance field, line width and line intensity) allowed us to determine magnetic and structural transitions. We have constructed a phase diagram T vs. x in order to contrast ESR results with those obtained by susceptibility and X-ray diffraction.
