Abstract
Undoped and Cr3+-doped KTiOPO4 (KTP) systems were studied by means of P-31 nuclear-magnetic-resonance measurements. The high-resolution P-31 isotropic -chemical-shift measurements were employed as a new probe in addition to th e laboratory and rotating frame spin-lattice relaxation-time measurements. As a result, two phase-transitional behaviors ascribed to the changes in th e dominant charge carriers were well characterized. Furthermore, it was fou nd that the Cr3+ doping of the KTP system results in significant shifts in the transition temperatures.
