Magnetic phase diagram and anisotropy in the one-dimensional quantum spin system Rb<sub>2</sub>Cu<sub>2</sub>Mo<sub>3</sub>O<sub>12</sub>
ORAL
Abstract
We report low temperature thermodynamic, magnetic and electron spin resonance (ESR) measurements on single crystal samples of a quantum spin chain material Rb2Cu2Mo3O12. In heat capacity measurement, phase transitions to magnetically ordered state are clearly observed, and the entire phase diagram is mapped out in detail. It is found that the criticalities of the transitions at lower and upper fields are dominated by three-dimensional order and one-dimensionality, respectively. The measured phase boundaries and ESR data prove that anisotropy heavily influences the magnetic state of Rb2Cu2Mo3O12 [1].
