Abstract
This is the first systematic ESR investigation of La(1-x)Sr(x)MnO(3) single crystals for Sr concentrations x < 0.2. The rich phase diagram of this compound, which is dominated by the Jahn-Teller effect of Mn(3+), is a matter of actual interest in connection with giant magnetoresistance phenomena. The ESR signal, which is due to both Mn(3+) and Mn(4+), directely probes the suppression of the Jahn-Teller distortion with increasing Sr concentration and reveals all characteristic structural and magnetic phase transitions.
